Do I need to register for Mobile PINsentry?
No. If you’ve already registered for a PINsentry card reader, you won’t need to register again to use Mobile PINsentry in the Barclays app. It may take up to 10 days for the Mobile PINsentry feature to become available.
If you haven’t, you’ll need to register for PINsentry and have received your card reader before you can start using the mobile version.
