Our technology

The Sentinel smartcard

The Sentinel card has a unique QR code printed on the front and when this is scanned by the Sentinel App, it automatically accesses part of the cardholder’s record in the Sentinel database. The relevant information about the cardholder is displayed on the App for the Controller of Site Safety (COSS) to determine their Authority to Work.

The smartcard is also compatible with Near Field Communication (NFC) devices when using the Sentinel APP to swipe the Sentinel Card. The NFC aerial on most phones is on the rear of the device, each model differs in where this spot is so some trial and error is required.  The card should be held in contact with the rear of the NFC enabled device whilst the card is reading the information held on the chip within the card.

The Sentinel Card can also be swiped using a compatible card reader and Sentinel software installed on a PC. (Software is free to download and can be found at the bottom of this page)

Your organisation might choose to combine more than one Swipe In approach, depending on your work for Network Rail.
