1, ID card (EM Card) Features
★ carrier frequency is 125KHZ (THRC12) or 13.56MHZ (THRC13);
★ card reader to transfer data to the modulation amplitude for the load;
★ card data encoding using strong anti-interference phase shift keying BPSK mode;
★ card reader data transfer rate to 3.9kbps (THRC12) or 6.62kbps (THRC13);
★ data storage by EEPROM, the data stored for more than 10 years;
★ data storage capacity of 64, including manufacturers, distributors and users of the code;
★ card number before the letters written after the card can not be changed, absolutely sure that the only card number and security;
★ T HRC13-chip package as the standard card shape than outside, according to application needs can be packaged into a chip and other shapes.

Second, ID card (EM card) works
    System consists of cards, readers and back-controller (see Diagram). Work process is as follows:
(1) reader carrier signal will be sent out via antenna;
(2) card into the reader's work area, by the card coil inductance and capacitance form a resonant circuit to receive the carrier signal emitted reader, card chip RF interface module generates this signal supply voltage, reset signal and the system clock, the chip "active";
(3) chip control module to read data from the memory modulation by the phase modulation encoded on the carrier, sent back by the card reader antenna;
(4) the card reader sends back the received signal demodulation, decoding computer sent back;
(5) background computer according to the legality of card number, for different applications to make appropriate treatment and control.

3, ID card (EM card) Application
    And contactless ID card (EM card) compared to non-contact type ID card (EM card) without plug cards, to avoid being exposed as a result of a variety of mechanical failure, which is easy to operate, fast, reliable and long service life outstanding advantages, especially for high traffic situations. THRC12/13 non-contact type ID card (EM card) can mainly be used in identification and addressing control, such as access control, security, attendance and other fields, but also extend the application to the exhibitions, parks, hotels, restaurants and other public places tickets , discount cards. And the production process, parcel post, air rail transport, packaging, transportation and other sectors of the logistics, electronic tags, security signs, one-off tickets and many other fields. Although it is a read-only cards, but the use of computer control and management background, even if the problem is related to the management fee can be applied in a certain range, such as canteen meals fee management. Specific applications, can be sent to the cardholder's personal data back the computer, and configure the application to establish a database, use the card number through the card reader will read the computer sent back from the database after the cardholder personal data, then operation should be carried out according to specific and therefore very broad range of applications.
