I have no end of problems because I cannot see there is no tactile way to know where to sign. Most rub off in a few weeks I'm told most shops seem to merely rely on pins and the back security number if you are doing it over the phone.
Unless of course, like me you have a chip and signature one in which case its hit and miss who actually knows they are legal or insist on you having a passport or driving licence, which would be a unique trick for a blind person. I had awful trouble with the apple store over this last one. Indeed I'm having to get a passport merely to be able to buy anything where their finance is handled by Berkleys, berk is well named. I told me maybe we blindies should all be microchippe as we are clearly second class citizens. Brian
Yes I know Barclays is an A byt it made me feel better.
