Any Credit/Debit Card Reader Experts?

JustKeepSwimming_2

I posted this thread on the credit card forum about my shopping being paid for by a different card some time ago, but haven't had an answer to say if what has happened is possible from a tech point of view.

I keep being told that it can't have happened, yet I remain convinced that it did as I have the receipt.

I've since been told that the card readers in the store have all "had a refresh" & am curious to know how card readers work & if they can go wrong - can anyone enlighten me please?

I understand the argument that it isn't cost effective for the banks to investigate what has happened, & I doubt I'll ever get to the bottom of who paid for my shopping, but I'm wondering if the whole chip & pin is a secure as we've been told (without wanting to sound like I'm bonkers ).

Thanks in advance.

Nope its not fully secure see the www.

With any technology currently in use today there will be vulnerabilities. Nothing is totally secure only difficult to circumvent and gain unauthorised access...

There has arguments for and against Chip & Pin including NFC for contact-less payments..

At the end of the day it is a computer and if there is any error in the logic within the software it generates errors.

Refresh usually means one of the following:

• Hardware Firmware Upgrade/Reload
• Software Upgrade/Reload
• All above
