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 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. 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.
