How do pinsentry readers work

OK so for a few days I have been trying to work this out. I took one apart and it just looks like a calculator. Are the codes already installed in it? I went into Barclays and asked, and her response was magic and lol. Wasn't impressed with the answer tbh!

So explain how it works. Always wanted to know this myself. Whether it's a radio transmitter or something? I can't imagine it's good security if the 8 letter codes are pre determined. You have to put your card in and a code and then it spits out a number having been through an algorithm. This result is input online and the banks server compares the number to its result from the same inputs, et viola!

Yeah my business account has one of these readers. Make sure we have their correct UK mobile number by using Barclaycard online servicing or by calling Or, check out our main page.

If you prefer to use text messaging, we can send a one-time verification code to your mobile. It's a small handheld device that generates a unique eight-digit code to help confirm it's you when making payments or servicing your account online.

Simply insert your card and tap in your PIN to use it. Entering this code gives you an extra level of security and protection. You won't need to use PINsentry all the time as there will be exemptions. The legislation includes Strong Customer Authentication SCA , which requires you to confirm it's you when you pay for things or service your account online.

PINsentry is one of the options to help verify your identity, giving you greater security and peace of mind. If this is correct, then it allows you in to the online banking. Once used it is dead, and you are left with 99 more codes. Eventually, once you start getting low on codes on the chip of the card, the cash point the next time you use it will issue another to the chip, and it a cycle that cannot be hacked. This is how it works without a internet connection.

It gets the internet connection from the cashpoint, and then works offline, just like email clients. Very simple, but effective. I note from one of the posts states that the card has say numbers installed by the Bank. But how does the account know which of the generated numbers is correct, Could it not give a hacker chances to gain access?

The PIN might be crackable. The card might be cloned? Do you know the answer? What is Mobile PINsentry? How to download and log in with Mobile PINsentry.
