MiFare Classic (13.56 MHz) tag assortment - 1KB

One of each of our favorite Mifare Classic 1K tags - 5 in total!

• Credit card size
• 1" diameter 'laundry' clear tag
• 1" diameter 'laundry' white tag
• Key fob
• Sticker

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 PN532 NFC/RFID breakout board and 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 our PN532 NFC/RFID breakout board or 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.

S50 chip specification:

• 1 KiloByte (8 KiloBit) non-volatile EEPROM storage
• Built in encryption engine with 48-bit key
• 4 Byte unique identifier burned into the chip
• 13.56 MHz frequency
