Radio Frequency Identification Technology (2)-International Standards

If you are only a smart card user, you generally do not have to pay attention to international standards, but as a professional developer of smart card, you should at least understand the relevant standards. International standards are generally set by Westerners. The original version is in English, and the so-called Chinese version is often a literal translation of the original version. In many cases, the actual meaning is not accurate. Therefore, if you want to see these standards, check the original version. The following describes only important international standards for smart cards. In the future, I may seldom mention these standards. If you do not read these standards, it will not affect your friends to continue reading them. However, the so-called "no rules, and no rules", I will only tell you here, the subsequent descriptions are based on these international standards.

I. ISO 7810: Specifies the physical characteristics of the identification card, such as the shape and size of the card.

Ii. ISO 7816: International Standard for ID card IC cards. This standard contains many parts and is currently being released and supplemented. 7816 is an international standard that must be followed by contact IC cards. Some of them are also applicable to non-contact smart cards.

The first part specifies the physical characteristics of a contact smart card;

The second part specifies the contact size and position of the contact type smart card;

The third part specifies the electrical signals and transmission protocols of the contact smart card;

Part 4 defines the interface organization, security, and commands for the contact smart card to interact with the outside world;

The fifth part sets out the naming and registration system for the contact smart card application;

Part 6 specifies the data elements for the interaction between a contact smart card and the outside world;

Part 7 specifies the command used by the contact smart card for structured query;

Part 8 defines the security operation commands for contact smart cards;

Part 9 specifies the card management commands for the contact smart card;

Part 10 specifies the electrical signals and reset responses of the synchronization card;

Part 1 sets out personal authentication for the Use of Biological Statistics;

Part 1 specifies the USB electrical signal interface and Operation Sequence of the contact smart card;

Part 1 specifies application management commands in multiple application environments;

Part 1 does not seem to exist;

Part 1 specifies the encryption information application. Amendment 1: the instance of the encryption information application.

Iii. ISO 10536: International Standard for password-coupled cards (CICC.

The first part specifies the physical characteristics of CICC;

The second part specifies the size and position of the coupling area of CICC;

Part 3 specifies the electrical signals and reset procedures of CICC.

Iv. ISO 14443: close to the international standard of PICC.

The first part specifies the physical characteristics of PICC;

The second part specifies the RF power and signal interface of PICC;

The third part sets out the initialization and Conflict Prevention algorithms of PICC;

The fourth part defines the transmission protocol of PICC.

V. ISO 15693: International Standard for sparse coupling cards (vicc.

The first part specifies the physical characteristics of vicc;

The second part specifies the air interface and initialization of vicc;

The third part specifies the vicc's conflict prevention and transmission protocol.

Vi. ISO 11784/11785: International Standard for animal identification code.

11784 specifies the encoding structure of animal identification signals;

11785 define some technical concepts of animal recognition.

VII. ISO 10373: Specifies the identification card testing method.

So many standards have brought a lot of people to the fore. In fact, as an RFID development and application, not all these protocols need to be viewed. First, if you don't create a card, you don't need to look at the physical part. The manufacturer just needs to know what it is like. The signal interface just needs to know about it, because each card usually has a dedicated interface chip, unless you build all the antenna-to-CPU interfaces with separate devices, you should spend more time studying the specification of the dedicated interface chip. Card communication protocols are what we should pay attention to most, because it needs to be implemented by developers in software, while the international standards for animal identification coding are used for animal identification cards, it specifies the encoding rules for cards to send animal identification information, smart card applications.
