M1S50 RFID tag 20mm anti-metal 13.56MHz

These Heavy Duty On-Metal NFC Tags features a ferrite layer to allow for uninterupted functionality when placed on metal, aluminum, or electronic surfaces. With a durable and waterproof ABS plastic housing a fast and reliable M1S50 chip with 144 bytes of usable memory, these tags are great for industrial and/or outdoor applications. A 3M adhesive backing as well as a 5 mm center hole, means these tokens can be adhered to or drilled onto a surface. This particular NFC tag model is commonly used for security access checkpoints as it can be easily mounted to metal-framed doorways. Tags come blank and are read/write ready -- once written, data can be "locked" so that the tag is read-only. If an NFC tag is "locked" it cannot be unlocked.

Compatible with both iPhone and Android devices.
