| 2. IC card section | (1) IC card reading and writing module | Working frequency 13.56MHz Communication speed 106Kbps |
| (2) IC card reading and writing function | Supports logical encryption cards, CPU cards, dual interface CPU cards/Mifare I, Mifare Pro And Pro-X; Support ISO7816 and ISO14443 TYPE A standards; Typical transaction time for IC card: ≤ 100ms; Non contact IC card reading and writing distance: 0-100mm; Read and write error rate of the reader: ≤ 0.00001; The triple DES encryption algorithm is used for bidirectional authentication between the reader and the card, and the data communication meets the requirements of relevant national standards. There are three types of sound and light alarm signals, indicating different types of situations: correct completion of reading and writing, reading and writing errors or failures, and reader/writer failures. Automatic sound and light alarm signals will be issued for illegal cards or when abnormal information is found in the card. The reader/writer should be equipped with standard library functions for reading and writing IC cards, password verification, and other operations. Support online program upgrades and provide online upgrade software. |
