Dual Frequency Chip PVC Proximity Smart Cards
UHF+ID 125Khz EM RFID Composite Card
00204519003113574 Electrical Characteristics
The capacity is 8K-bit EEPROM
Storage divided to be 16 sectors/each sector 4 blocks/each block 16 bytes, the block is the access unit.
Each sector set an independent passwords and access control
Each card has an unique 32 digits serial number precise recognition different cards, support multi-card operation
No need power supply, built-in antenna, encryption control logic and communication logic inner circuit.
The data storage period 10 years, rewritten 100,000 times, unlimited read times. Working temperature:-20℃~50℃
Communication rate: 106KBPS Working frequency: 13.56MHZ
Read/write distance: within 100mm (also rely on different reader)
ID card in the weak system is generally used as access control or parking system user identification, because it does not have built-in power
supply, when used without contact and long life, so weak in the system has a wide range of applications. The emergence of ID card basically
eliminated the early magnetic or contact IC card.
But because the Id card can not write user data, the record content only card number can only be written one-time by the chip factory,
developers can only read out the card number to be used, can not be based on the actual needs of the system to develop a new number
management system. At the same time because the id card has no content, so the card holder's authority, the system function operation
to completely rely on the computer network platform database support.
