Also, sellers wish to have contracted the credit card company the credit cards of which potential customers usually carry along. For both, basically, it is all the same which credit card this is.

Things are a bit more difficult for non-verbal communication, for example data transmission between computers-both sides have to use the same or compatible protocols. Again, what matters is the protocols to be the same for both sides.
