I have a VISA and have used it without issue. I wanted a spare in case this one got lost while abroad or stolen. Revolut wouldn’t let me have another VISA so I had to get a MasterCard. I have just had that and went to use it (chip and pin) to activate the contactless. Costco rejected the card BUT they did accept the VISA. This kind of makes the MasterCard useless as a backup. My query though is what is the MasterCard classed as?
Costco accept debit card or Amex credit card. It seems they consider the VISA as debit but the MasterCard as credit, hence its rejection.
