How to read all information from 125 khz RFID card?
It is the reader device that gives you the infomation. The reader is programmed to act like a keyboard and it only gives you the card id. Keyboard communication is one-way. If you want to do more like reading and writing, you'll need another reader device which is capable of reading and writing. Or maybe you can load some firmware to your card-reader-device to act to support two-way communication.
