How does a PINsentry card reader work?

You’ll need to use your PINsentry card reader to authenticate yourself for online transactions and banking. When you insert your card into the reader, the device will prompt you to enter your 4-digit PIN number. It will then generate a unique eight-digit code for you to use to complete your transaction or log in to your account. A different code will be generated each time you use the PINsentry card reader.
