SMS Verification
I’ve received an email today from Barclaycard with the following:
“From time to time, to make sure it’s you who’s using your Barclaycard online, we’ll send you a text with a verification code for you to use on the Verified by Visa screen that’ll pop up on your payment page.”
The proprietary nature of mobile phones with the hardware specifications and the software being closed off from inspection or audit and considered to be trade secrets make my phone and my tablet the least trusted devices I own and use.
