SALTO XS4 Lock System

Basically there are three reasons a reader might not react;

  1. the chip is incompatible and doesn’t actually read.

  2. the reader reads the chip but at the application level it’s not compatible, or not authorized and the reader application is configured such that readers are purposely not responding.

  3. the chip is compatible and the reader is configured to respond, but the antenna design isn’t great and can’t successfully power the implant.

Have you used the xLED on the readers which don’t show a.response?
