When trying to process on Swipe Simple, here are a few common errors and the recommended steps to resolve them:
Certificate Pinning Error or Unverified BroadPOS Device
For certificate pinning failure error, or an error about peer certificate chain, try the following in this order:
Update the Swipe Simple App from the PAX Store App (version 7.27 as of Aug 2026).
Restart your device.
You could update the TSYS Sierra app.
First, close any open batches
Next, update the TSYS Sierra App to version .44E (as of Aug 2026). Version .45 has not yet been certified.
If it still isn't working, you may need a firmware update, which can take up to 20 minutes.
From the home screen, click on the PAX store app
Click on the three horizontal bar icon in the top left hand corner
Select 'Firmware Update'
Select 'Check Update'
Install any available updates
After updating, restart the device again
