ID Card
Basic Introduction
The ID card is a read-only non-contact IC card, also known as a low-frequency card. It relies on the card reader to sense power and read the unique card number stored in the chip EEPROM. The card number is written before the card is sealed, and the card cannot be rewrite later.Like the magnetic card, the ID card only uses the "card number". Except for the card number, the card does not have any security function, and its "card number" is public and exposed.It is widely used in radio frequency identification fields such as patrol systems, attendance systems, access control systems, residential property management, and enterprise card systems.
Product Features
◇ Carrier frequency is 125KHz (THRC12) ；
◇ Modulation mode of the data transmitted is load amplitude modulation from card to reader；
◇ The data encoding in the card adopts the BPSK phase shift keying method with strong anti-interference ability；
