My bank mainly issues Visa cards. I’ve had multiple cards throughout my life, and I’ve never had a master card before. I’d like to just add this feature to my existing cards that I already have set up for payments. Completely off topic: What I really want in life is: 1. If I could have a virtual credit card that could act as a proxy card and would let me use different cards based on the items I was purchasing (ex: if I’m getting gas, one of my credit cards may give better rewards) 2. A virtual mailing address that would resolve to my current address when used with any shipping provider. I move every few years and hate mail forwarding and updating my address everywhere.
