Turn almost any smartphone, hard hat, badge holder, equipment case or smooth surface into a convenient RFID access credential with the AuthorizID MIFARE Classic 1K Compatible Adhesive Sticker Tag. These compact 25mm black NFC sticker tags are specifically designed for access control, parking systems, time and attendance, lockers, vending systems and other RFID applications requiring MIFARE Classic 1K compatibility. Unlike standard NFC stickers that often stop functioning properly when attached to metal or phones, these tags include an integrated ferrite anti-metal shielding layer on the back of the credential.
