Exactly this. Was purchasing something from Next yesterday using a Barclay credit card when a security box appeared instructing me how to use a card reader. There were no other options for authentication. I tried several times. Rang Barclays and was told it was a new security measure. I asked why a code wasn’t posted to my phone. At first she said they couldn’t have my phone number and then saw they had. They could send me a card reader which will take up to 10 days. Went to the bank today to ask if they had them but they can only order them. As I had used an iPad I thought I would try my Mac but the result was just the same. After this I used another card (not Barclays)and was given three options for authentication so all was well. It seemed very strange that if Barclays requires a card reader now there was no prior warning and you can’t even pick one up from the bank. Am I alone or has anyone else had this happen to them?
