ID Card Introduction

★ Basic Overview
　　ID cards shall be THRC12/13 Read-only non-contact cards, ID cards can generally be divided into two major categories, namely, ID cards and ID after the thin card, the fundamental difference is not the same as the thickness of the card, the internal coil around the different works the same, it is powered by reader and read out the sensors is stored in the EEPROM chip, the only card number, card number, before the write-once the sealed card, seal card can not be changed. Passive and avoid contact with the chip, the two most prominent characteristics of RF interface circuits is a critical core technology, which receives RF energy from the reader, in order to generate power and clock chip, using phase shift keying and load amplitude card and reader technologies such as between the wireless communication.

★ Main Features
1, carrier frequency of 125KHZ (THRC12) or 13.56MHZ (THRC13); card reader to transfer data to the modulation method for the load amplitude modulation;
2, the card data coding using anti-jamming ability of the BPSK phase shift keying mode;
3, the card reader data transfer rate to 3.9kbps (THRC12) or 6.62kbps (THRC13);
4, data storage using EEPROM, data retention for more than 10 years; data storage capacity of a total of 64, including manufacturers, distributors and users of code;
5, card number, card before the closure can not be re-written after the changes, make absolutely sure that the only card number and security;
6, THRC13 addition to package into a standard chip card shapes, can be packaged into a chip according to application needs a variety of shapes.

★ can be divided into categories
1, ID card thickness: thickness 1.8mm, standard card size, is the most economical RF IC cards, with ID numbers, with a portable hole, you can screen printing LOGO text information;
2, standard thin card: thickness 0.8mm, standard card size, you can offset printing, screen printing, printing photos;
3, non-standard thin cards: the thickness of 1.05mm, the standard card size can be offset, screen printing, print photos.

★ Applications
　　Compared with the contactless IC cards, contactless ID cards do not need swap cards, to avoid poor contact caused due to a variety of mechanical failure, which has a user-friendly, fast, reliable and long service life outstanding advantages, especially for the flow of people big occasions. Typical Applications: Canteen 售饭 system, patrol system, attendance systems, access control systems, business areas of radio frequency identification card system.
　　THRC12/13 non-contact type ID card can be applied to the main identity and addressing control, such as access control, security, attendance, and other areas can also be applied to extend exhibitions, parks, hotels, restaurants and other public places of the tickets, discount cards and so on. As well as the production process, parcel post, air rail transport, product packaging, transportation and other sectors of logistics, electronic tags, security signs, one-off tickets and many other fields. Although it is only a read-only cards, but the use of computer control and management background, even if management issues related to fees and charges can also be in a certain range of applications, such as canteen meals charge management. Specific application, the cardholder's personal information can be sent to the background the computer, to establish a database and configure the application software, when used through the card reader will read out the card number sent to the background of the computer, transferred from the database out of the cardholder's personal data, and then operate according to specific applications, so application is extremely wide.
