"I did, and then most of the providers dropped MasterCard and converted them into Visa cards"
Why on Earth has someone downvoted that? From my experience, what AC said there is true. I have quite a few cards - they were a mix of different banks and spread between Visa and Mastercard. Now only one is Mastercard. (For example, the one attached to my main personal bank account was originally a Mastercard and was replaced with a Visa when the bank switched.)
