Configure Airfob Patch and Tag

Device overview

The Airfob Patch and Tag upgrade an existing access control reader or door lock to work with BioStar Air mobile credentials.

• Airfob Patch: An energy-harvesting device for wired readers and intercoms that attaches without additional wiring.

• Airfob Tag: Fits battery-powered devices such as door locks using a coin-cell battery.

Info

• The Airfob Patch and Tag are compatible with MIFARE 1K technology but are not compatible with 125 kHz low-frequency readers or locks.

• They authenticate encrypted Bluetooth BioStar Air credentials from a mobile device and operate by emulating a MIFARE RFID signal. They attach to readers and locks with tape and require no wiring.

Customers who began using BioStar Air access control before May 2025 may still be using the Airfob Space app, which has since been rebranded as the Suprema Pass app. Both apps offer identical functionality and are fully compatible. There is no need for existing users to switch — mobile credentials work seamlessly across both.
