Java Card is a microprocessor-based smart card, which consists of multiple elements: hardware, Java Card operating system, security module (card manager) and one or more Applets at the time of release.



Hardware

There are various hardware manufacturers, but, it should be noted that the most popular are NXP and Infineon. The two silicon manufacturers ship millions of microprocessor chips worldwide each year. They have been certified by EMVCo, Visa, MasterCard and UnionPay International to provide you with a hardware platform with first-class security.



operating system

Java Smart Card OS is an operating platform that utilizes hardware functions and allows applications (small programs) written in the Java programming language to run on the card. Java Card is an open platform, and its standards (and development kits) are available for free from Oracle’s Java website.



Card manager

One of the main functions of the microprocessor card is its security function. A separate area of the chip is designated specifically for this purpose, the “card manager”. This is an application that permanently resides on the chip, has the function of performing card and applet management, and is a gateway to a security element (called a security domain). This central component is defined by another open platform standard GlobalPlatform.



GlobalPlatform (globalplatform.org) is an independent standards body run by its members. Members include Apple, Oracle, Samsung, American Express, Gemalto, NXP, HID, Visa, Infineon, MasterCard, etc.



Applets

An applet is a program that runs on the card that the user (or terminal) will interact with. Each card can load one or more small programs at the same time, depending on the available storage space of the chip. Not all applets have to be the same, their size and functions can be different. The applet can use the card manager for security purposes (such as authentication), or it can write its own security domain into it. Once the applet is installed, the terminal can communicate directly with it without needing to know the card manager. When you put the card in the terminal, you can select a small application, or you can select a small application as the default application.



When choosing a Java Card product that meets your requirements, there are many considerations to consider. The universal smart card can guide you through these operations in order to specify the correct card for your project.



starting point

A good starting point is to answer the following questions:

What do you want to use the card for?

What applications will the card be used for?

Do you need contact, non-contact or dual interface?

How much storage space is needed on the card?



Getting answers to these questions will help find the correct hardware, operating system, and model of any particular Applet you may need. Developers who write their own applets only need to care about the specific hardware functions required and the relevant specifications of the Java Card OS and GlobalPlatform.

In the vast ocean of the digital world, we navigate the intertwined waterways of physical and virtual, exploring more efficient and secure communication methods. Every technological development is as brilliant as a star, and Radio Frequency Identification (RFID) technology stands out among numerous technological achievements with its unique brilliance. It quietly changes our lives with an invisible hand, from supermarket checkout to highway toll collection, and then to contactless payment - almost everywhere, leading us on this journey.

RFID technology is a wireless communication technology that enables contactless transmission of information through radio waves. It not only simplifies our daily lives - from payment cards to logistics tracking, we cannot do without its presence; However, as the application scope of this technology continues to expand, its potential security issues have also surfaced: identity theft, data leakage... These issues, like ghosts, threaten the peace and order of the digital world. In the context of global information security, players are playing an increasingly important role. To discuss the security of RFID, it is necessary to mention its key link: security authentication. Therefore, ensuring the security of RFID technology has become an urgent task, and this has given rise to the key process of three security authentication.

When it comes to security authentication, people often think of complex passwords and complex operations. However, in the world of RFID, everything becomes different. The first security authentication here is not initiated by the user, but automatically performed by the system. When a card or item with a chip approaches the reader, the first step is the detection phase. If the match is successful, it enters the activation state and there is a short time window for both parties to exchange data. This non-contact startup process greatly facilitates the user's operating experience and lays the foundation for subsequent security measures.

Next is the process of the second security certification. This time it's the user's turn to participate. Users need to enter a Personal Identification Number (PIN) or other forms of identity verification to prove their ownership of the card. This step is equivalent to an access control, only those who know the correct method of opening the door can further access the information inside the card or perform transactions and other operations.

Finally, we come to the third security certification. This is an additional layer of protection established for high-risk operations. For example, in certain financial transactions, even after the first two identity confirmations, third-party verification methods such as SMS verification codes or phone verification may still be triggered. This multiple protection mechanism makes it difficult for criminals to obtain all benefits smoothly even if one layer is cracked.

When we turn our gaze back to the real world, it is not difficult to find that behind every progress lies the result of countless explorations and experiments. As demonstrated by RFID technology, even a small piece of paper thin label may contain countless wisdom crystals and expectations for infinite possibilities in the future.

With the development of technology and social progress, future RFID technology will become more intelligent and deeply integrated into daily life. At the same time, we also believe that with the emergence of new challenges, corresponding solutions will emerge one after another, making this digital era more convenient, intelligent, and secure.

RFID PRODUCTS: there have RFID card, RFID wristband, RFID tag and RFID reader.

With the acceleration of urbanization and the increasing demand for residents' travel, the number of electric bicycles has grown sharply. This directly led to a sharp increase in management difficulty. In busy urban traffic, electric bicycles have become an important means of transportation, but their rapid increase makes it difficult for regulatory authorities to fully cover and effectively manage them.

Industry pain points

1. Electric bicycles are parked randomly, occupying pedestrian walkways indiscriminately, obstructing pedestrians' travel, and increasing traffic risks. Inconsistent parking direction,

2. The backend site does not match the actual parking space line, and users return their bikes outside of the planned parking space after cycling, which increases the workload of operation and maintenance personnel in moving bikes and increases operating costs.

3. The safety awareness of electric bicycle drivers varies greatly, and some drivers lack knowledge of traffic regulations and do not comply with traffic rules. This non-standard driving behavior not only threatens the safety of the driver themselves, but also poses potential risks to other traffic participants

4. Severe cases can block fire exits, pedestrian evacuation routes, etc., posing serious fire rescue safety hazards, delaying the best time, and posing a threat to people's lives and property!

Solution

To standardize the parking of shared electric vehicles, strengthen the supervision and management of shared electric vehicles, reduce the management costs of operation and maintenance enterprises, promote orderly parking of shared electric vehicles, and avoid safety hazards such as affecting the city's appearance, obstructing traffic, battery fires, loss and damage caused by disorderly parking of vehicles. Therefore, Shenzhen Wanquan Intelligent R&D utilizes intelligent sensing RFID wireless radio frequency identification technology to effectively provide product solutions for issues such as electric vehicle parking management.

1. Vehicle identification and traceability

Unique identification: The RFID electronic license plate is embedded with ultra-high frequency RFID electronic tags, which write vehicle information and ensure data security and reliability. It is not only anti-counterfeiting and anti duplication, but also has a unique identification QR code printed on the outer surface, which can be used as the unique identification of the vehicle, effectively solving problems such as forgery, alteration, and obstruction of license plates, thus achieving traceability and supervision of electric bicycles.

Information recording: RFID tags can record vehicle license plates, models, colors, chassis numbers, insurance and other information, and can flexibly add other information according to needs, providing comprehensive and accurate data support for vehicle management.

2. Improve traffic management efficiency

Automatic identification and tracking: By setting up high protection RFID readers on busy road sections, automatic identification, positioning, tracking and management of electric bicycles can be achieved, improving the intelligence level of traffic management.

Illegal behavior capture: Combined with electronic police cameras, it can automatically capture illegal behaviors such as running red lights, going in the wrong direction, and not wearing helmets around the clock, achieving remote law enforcement and improving law enforcement efficiency and accuracy.

3. Assist in smart transportation and urban management

Smart Transportation: With the continuous advancement of autonomous driving and intelligent vehicle networking, RFID electronic license plates are very suitable for integration into the collaboration of "people, vehicles, and roads", helping the development of smart transportation and promoting the vigorous development of the automotive industry.

Urban management: The application of RFID electronic license plates can also be combined with community access control systems, smart facial recognition systems, etc., to achieve comprehensive safety management of electric bicycles and improve the level of refinement in urban management.

4. Anti theft and security measures

Anti theft management: The application of RFID electronic license plates can help solve the problem of electric bicycles being stolen and robbed. After a vehicle is stolen, RFID technology can be used to trace the vehicle's trajectory, which helps the police quickly recover the stolen vehicle and ensure the safety of the owner's vehicle property.

Charging and Parking Management: The RFID electric bike rental system relies on management base stations (RFID card readers) installed in unit corridors or elevators, battery identity chips, and access control recognition linkage systems to achieve community parking, safe charging, and household control of electric bicycles with one vehicle, one pool, one code, and one person identity binding. When an electric vehicle (battery) enters the unit door or elevator, the system will identify and prevent it from causing fires and injuries due to charging at the entrance.

With the high emphasis on environmental protection, the importance of environmental protection can be imagined. It can not only coordinate the relationship between humans and the environment to protect our living environment, but also ensure the sustainable development of the economy. The rapid development of urban construction and environmental treatment have always troubled many management departments. The number and distribution of environmental sanitation facilities, the execution guarantee of garbage collection frequency, daily garbage production and cleaning guarantee, timely garbage transportation, and timely scheduling will become important components of health hearing supervision. Environmental protection work mainly utilizes RFID technology to collect information from various parts, establish intelligent sanitation platforms, and help the development of smart cities. RFID technology has become an important helper for intelligent sanitation garbage bin data collection.

Due to the large number and wide distribution of garbage sanitation facilities, precise and real-time monitoring cannot be achieved; The serious accumulation of garbage in urban garbage bins, the inability to accurately grasp the situation in public places, and the inability to timely understand the efficiency and quality of task execution by relevant personnel; The status information of sanitation vehicles cannot be obtained in real time, and problems such as not following the prescribed route for collection and transportation, and speeding operations cannot be eliminated; The inability to ensure timely transportation and scheduling of garbage poses many challenges for managers, and RFID technology has become an important helper for intelligent environmental sanitation garbage bin data collection.

Garbage clearance supervision is achieved by installing ultra-high frequency RFID readers and writers inside the garbage truck, and attaching ultra-high frequency RFID tags to the garbage bin. When a garbage truck starts loading and unloading garbage, the RFID reader on the garbage truck will read the RFID electronic tag on the operated garbage bin.

Install RFID readers and writers at various community sanitation stations to collect RFID electronic tags installed on trash cans. The RFID electronic tags are bound to detailed information about the location of the trash cans. At critical locations along the cleaning path, install geographic location tags. When the sanitation station passes by, the tag information is read to obtain location information, which is beneficial for the system to plan the optimal route. Install an ultra-high frequency integrated reader and writer on the sanitation vehicle responsible for garbage removal. By installing the ultra-high frequency RFID reader and writer on the sanitation vehicle, electronic tags on each garbage bin or hopper can be read to track the working status of each vehicle. Install GPS locators on sanitation vehicles to determine the location and route of each vehicle (sprinkler, road sweeper, garbage truck, etc.). In this way, the system will record the time and ID information of each trash can operation, with specific unique identity information,

RFID technology collects data from various stages, quickly understands the distribution of facilities in garbage classification management, greatly improves the management efficiency of each stage in environmental sanitation operations, enhances work efficiency, and can achieve timely cleaning of garbage. Provide strong data support for the digital management of urban garbage cleaning work. Digital sanitation management provides real-time monitoring, intelligent analysis, data support, and precise scheduling for sanitation operations, which can effectively improve the level of precision and information management, improve the efficiency of urban sanitation work, ensure work safety, and achieve better economic and social benefits.

Although NFC is similar to RFID in many respects and is based on RFID, it is an independent concept. In the case of RFID with passive and active tags, active tags can be read from a relatively long distance, while NFC, as its name implies, works in the near-field region of the electromagnetic field.

RFID still exists and will be in the foreseeable future. NFC is a direct development of RFID, and you might consider parallel branches. At the most basic level, NFC is usually two inductively coupled devices whose communication is performed by modulating the power absorbed by the passive device. Passive RFID absorbs RF power and then uses it to transmit data back to the reader-Active RFID can use its own power source to transmit data back to the reader. As with NFC, there are always exceptions to the rule-5 NFC tags have a longer working distance (up to 1 meter).

In the most typical implementation of NFC, a device is an active device, acting as a master device in communication and creating a modulated RF near field that will power passive slave devices. Active devices usually use the name of the reader, while passive devices are called tags. Common examples of tags include stickers and embedded systems. The most common NFC readers you might see in your daily life are smartphones or payment terminals.

Near Field Communication
In a typical RF communication, a transmitting antenna transmits RF signals into free space, and an antenna with at least λ/4 (quarter wavelength) is required to be effective. When the distance between two RF devices exceeds 2λ (two wavelengths), for example, about 245 mm (10 inches) for 2.4 GHz signals, they can usually communicate with each other.

Instead, NFC communicates in a spatial near-field area below λ/2 (less than half of the wavelength). Two near-field devices are used as two coils of a coupled inductor or transformer wound on a common magnetic core.

NFC technical parameters
Since NFC tags operate in the near field, the technical features and specifications are completely different from the more traditional far-field-based wireless technologies that you may be more familiar with. Let’s look at some interesting technical data related to NFC and how to compare it with far-field wireless technology.

Working distance

Although a dedicated point-to-point device can reach more than 100Km in compliance with the standard, it is estimated that the typical maximum outdoor range of a 2.4GHz WiFi device is about 50 to 75 meters. When a Bluetooth device runs on the same 2.4GHz WiFi, it will trade off bandwidth to increase power consumption, and expand to more than 300 meters for version 5.0. The range of LoRa equipment can exceed 10Km, its power consumption is much lower than these two technologies, and the bandwidth is very limited.

MHz is a unit of measurement that one cannot expect to find in the wireless specifications of modern smartphones. iPhone 11 has a communication frequency of up to 8GHz, and 60GHz WiGig devices are becoming more and more popular in the market. NFC uses a different method to reduce power consumption, range, price and frequency.

Tag type 4 mainly supports functions that perform calculations on the basis of storage and retrieval, as well as advanced security functions. Finally, if you need to read for a long time and allow users to interact with the tag through a smartphone, you will need tag type 5.

If you are building a nfc reader for a custom application, the type of label you use will most likely depend on the application and the labels that can be purchased, rather than choosing a specific label type. If you want to build a custom tag, you will usually make a choice for you, because the NFC IC used for tag implementation will determine the tag type.

NFC Forum Mark Type 1
As shown by the numbers, NFC Type 1 tags are the simplest and very cheap of all NFC tag types. Typical Type 1 tags support read-only or write-once operations. However, models with R/W capabilities can be used, they usually have about a hundred bytes (maximum 2 Kbyte) of memory and have a relatively slow 106kbit/s bandwidth. Typical applications include stickers, marketing, product tracking, so these labels are of little significance to ordinary electronic engineers.

The standard adopted by NFC Type 1 tags is ISO-14443A.

NFC Forum Tag Type 2
Similar to Type 1 tags, NFC Type 2 tags only support ISO-14443A in read-only and read-write applications. Many Type 2 ICs provide energy harvesting functions and I2C connections to external microcontrollers. However, Type 2 tags are commonly used as stickers, cards and tickets.

As mentioned above, Type 2 tags are the most common tags on the market, with a wide range of shapes and sizes, and can be used for tags attached to cable ties.

NFC Forum Mark Type 3
Type 3 tags based on the Sony FeliCa protocol are mainly used in Japan and Asia. In related Japanese markets, this tag type is often used for electronic money, identification, bus tickets and similar applications. The adoption of this standard in international electronic goods is restricted, and its main purpose includes supporting older versions of applications.

NFC Forum Tag Type 4
Type 4 tags compatible with ISO-14443A and ISO-14443B protocols have added support for the ISO-7815 standard for smart card identification. These tags can modify the data contained in its memory and are commonly used in security, identification and payment applications.

NFC Forum Mark Type 5
The Type 5 label is the latest specification to be released. The underlying physical layer is different from all other NFC tag types because it is based on RFID technology (ISO-15693) instead of ISO-14443A, allowing a maximum reading distance of 1.5m. However, like any other NFC tag type, the maximum length of a customer’s NFC device (such as a smart phone) is limited to 10 cm, and interaction with further places requires a special reader.

Types of NFC interaction
NFC supports three main communication modes: read/write, peer-to-peer and card emulation.

Read/write mode
The read-write mode is the simplest and most common mode of operation in the NFC standard. The NFC tag implements a memory whose content is usually composed of data in NDEF (NFC Data Exchange Format) format. Readers can read or write the contents of such memory.
The definition is very simple, but like most simple concepts in electronic products, it has a wide range of uses.

When an NFC tag has a complete SoC (System on Chip) function or is connected to an external microcontroller, it can usually be accessed not only by the reader, but also by the tag itself. In this case, the tag acts as a dual-port memory, just like a database accessed by two computers. In addition, the tag itself can be powered by the NFC reader and/or auxiliary MCU. Therefore, no matter where you visit, Tag can always be powered, just like a database hosted somewhere on the Internet.

Peer-to-peer model
In peer-to-peer mode, two active devices communicate with each other through one of the following two methods.
One device can be simulated as a tag, and another device can be simulated as a reader. This situation is obviously a master-slave solution. It is very suitable for systems with “smart” and “clumsy” parts, such as the main microcontroller communicating with a smaller auxiliary MCU through a physical barrier. This mode also allows the system to maintain compatibility with smartphones, because the smartphone itself can act as a reader, and the embedded device can act as a tag.

Realizing a peer-to-peer network through a protocol called LLCP (Logical Link Control Protocol) is a more abstract method, but it is also more flexible to connect. The LLCP protocol is designed to allow arbitrarily flexible communication between two active devices similar to BSD sockets, and many embedded and Unix programmers are familiar with this protocol. Uniquely, the LLCP protocol allows rapid migration of existing protocols, such as Modbus, RS485, CAN, LIN or UART via NFC connections, thereby realizing novel communication methods.

The disadvantage of exchanging data through the LLCP protocol is the lack of support for smart phones, which can only be delegated to embedded-to-embedded communication or embedded-to-PC. If you want to build a custom NFC application, or you can use NFC to meet project requirements without smartphone integration, then if you need a short-range wireless connection, LLCP may be what you want.

The part 1 of the depth of NFC tag types
