Description – Application

The WIREPAS 5.1-KF001 KEYFOB is fully compatible with Wirepas5.1 technology and is designed to full fill all requirements for people flow management and secure access control use cases

Thanks to its ultra-low power consumption, the tag guaranties un-surpassed battery lifetimes  and on top of that its CR2032 battery can be replaced.

Its high precision accelerometer sensor permits to detect any movements, vibrations, shocks or a specific fall. The accelerometer parameters are configurable in order to adjust them to the final needs of the application.

An optional NFC function can be added in order to provide extra functionalities as registration, access control or micro-payments.


The WIREPAS 5.1-KF001 KEYFOB can be proposed with:

  • NFC function to provide extra information on the asset (Manual, Last date of maintenance, Location) and/or easy pairing function
  • LED

The WIREPAS 5.1-KF001 KEYFOB can be laser engraved or silkscreen printed.
