RFID Sticker Coin Tag 25mm 125kHz (EM4100 Compatible Passive RFID Tag)

The RFID Sticker Coin Tag 25mm 125kHz is a compact low-frequency passive RFID tag designed for access control, attendance systems, asset identification, and automation applications. Operating at 125kHz, it is compatible with EM4100-compatible RFID readers and requires no internal battery, drawing power directly from the reader's electromagnetic field.

The 25mm round coin-style design features a strong adhesive backing for quick installation on surfaces such as plastic, glass, wood, and other non-metallic materials. Its durable PVC construction and long data retention make it suitable for long-term indoor RFID identification and embedded system projects.
