Do I need to plug the PINsentry into my computer?
No, your PINsentry card reader is wireless and battery powered. The card reader uses your Barclaycard details to generate a unique eight-digit code that's only valid at the time you need it. We'll never email you asking you to enter details to synchronise the PINsentry card reader.
The battery should last for between 5-7 years (or between 2-3 years for audio card readers).
