I think they will tend to disappear, and in fact they are already changing. The ones I have now don't have a space to sign on the back like they used to. With CBDCs and mobile phones, I think they will disappear.
I'm pretty sure card companies will switch to a virtual model after the launch of CBDCs. Plastic/metal physical cards will become a thing of the past. You'd get a virtual card number and that's it. Just like they've been doing lately. Perhaps, they will make a partnership with the central bank to provide CBDC services for the people. Who knows?
Despite the fact that digital payments will become a part of our daily life in the future, it's going to take a very long time before paper money and plastic cards get phased out. Seniors will be the first ones to reject such a change. Younger generations will embrace the revolution. As long as we're able to experience true financial freedom (through Bitcoin), nothing else matters.
