This app is designed specifically to read Sentinel smartcards for Network Rail’s Sentinel system.

It allows anyone to check their own Sentinel card and allows authorised card checkers to authenticate their team as well as undertake spot checks and check TVPs.

When online, the app shows the most up to date information for each cardholder either by scanning the card’s QR code or by reading the details stored in the smartcard using NFC. Even without mobile internet access, the information stored on the card can still be accessed, any recently scanned card details can also be reviewed, and all checks will be stored and uploaded to the database when back online.
