MiFare Classic 13.56MHz RFID NFC Card 1KB

MiFare Classic 13.56MHz RFID NFC Card 1KB

This is a blank MiFare Classic card - often used for train/bus passes but also found in other systems where a proximity card is desired. The tag contains a NXP S50 chip and an antenna, and is passively powered by the reader/writer when placed a couple inches away.

Description: This is a blank MiFare Classic card - often used for train/bus passes but also found in other systems where a proximity card is desired. The tag contains a NXP S50 chip and an antenna, and is passively powered by the reader/writer when placed a couple inches away.

These can be read by almost any 13.56MHz RFID/NFC reader but make sure it can handle MiFare cards as there are a few other encoding standards (like FeLica) They are tested and work great with both our SM130 Mifare Module and the Adafruit NFC/RFID Shield for Arduino. These chips can be written to store up to 1 KB of data in writable EEPROM divided into banks, and can handle over 100,000 re-writes. You can use the Adafruit NFC/RFID Shield for Arduino to read and write data to the EEPROM inside the tag.

There is also a permanent 4-byte ID burned into the chip that you can use to identify one tag from another - the ID number cannot be changed.

Specification:

1 Kb non-volatile EEPROM storage
Built in encryption engine with 48-bit key
4 Byte unique identifier burned into the chip
13.56 MHz frequency
