This app is designed specifically to read new Sentinel smartcards for Network Rail’s new Sentinel system.
For more information visit www.railsentinel.co.uk
Please note: ONLY new Sentinel smartcards can be read this way – not NCCA-Sentinel cards.
The new Sentinel app allows anyone to check their own smartcard and also allows authorised card checkers to authenticate their team as well as undertake spot checks and check TVPs (Track Visitor Permits).
Depending on the Android smartphone used, smartcards can either be checked by scanning the QR code on the front of the card/ TVP or by reading the microchip within the smartcard, using NFC (please note: TVPs can only be checked by scanning QR code).
This app can be used with any Android smartphone or tablet (Android 4 and above) with a rear-facing autofocus camera and NFC. Sentinel smartcards can be read securely using NFC, as these devices read information from the smartcard’s microchip electronically. Internet access is not required to read smartcards using NFC. The smartcard’s microchip can be checked using NFC with no internet availability whatsoever. However if internet access is available when reading a card using NFC, any updates for that card from the new Sentinel database are transferred automatically to the smartcard.
All smartcard checking activities are uploaded automatically to the database when an internet connection is present or will be uploaded later when connectivity is restored by re-launching the app.
To use NFC, make sure it’s enabled in the Wireless & Networks settings of your smartphone before you attempt to read any cards.
The application is easy to use:
1. Open the app.
2. If using NFC, hold the new Sentinel smartcard to the back, near the top, of your device OR click the QR code button and focus the camera on the card’s QR code.
3. Confirm the sponsor for today.
4. Depending on the card presented, either the card itself will be shown or a menu of options will be displayed for authorised card checkers.
5. Follow the on screen options.
Please note does not work with Galaxy S3 Mini
This version resolves a specific known issue on some devices due to the recent upgrade to Android KitKat. This issue would cause the device to crash upon reading a card. We are aware of other reliability issues introduced by the upgrade to KitKat and are monitoring the situation closely.
