有誰知道rfid 125KHz r/w card with user memory more than 1Kbyte?

# a8 {: m& f* g) K. b1 n9 }Does anybody knows if there is rfid 125KHz r/w card with user memory more than 1Kbyte (8192 bits). I have used the T5557 from Atmel but the memory is too small (about 330 bit) I have found some other codes from Atmel and EM marine, but the free user memory is about 512 bit or another one somewhere near 912 bit.

据我所知，没听说过125KHz同时容量又在8kbits的RFID
一般来说，如果配置如此大的EEPROM的话，那么一般都会采用较高的频率，例如13.56MHz，否则的话，但是全部读出8kbits的数据差不多就要2 seconds了（假设数据传输速率为125/32=4kbits/s），好像难于接受
