The Identiv 4090 Proximity Adhesive Disc is a compact, versatile 125 kHz credential designed to convert existing items into access control credentials. Comparable to the HID® 1391 MicroProx Tag, the Identiv 4090 provides a cost-effective and reliable alternative for a wide range of applications.

Featuring a strong adhesive backing, this proximity disc can be easily applied to key fobs, access cards, mobile devices, or other non-metallic surfaces, allowing it to function just like a traditional proximity card or key fob without the need to reissue credentials.

Operating on 125 kHz proximity technology, the Identiv 4090 integrates seamlessly with existing legacy systems and new access control installations. It can be programmed to match formats used by leading brands including HID®, Indala®, XceedID®, AWID®, Keyscan®, Honeywell®, AMAG®, GE/CASI®, and DSX®, ensuring broad compatibility.
