Notice that these “serial numbers” are very similar to the ones we embedded in the single-use credentials above. Each Resource (website) can keep a list of each SN value that it sees, and sites can reject any “show” that repeats a serial number.

However, repetition becomes inevitable if the User ever “cheats” and tries to show the same credential N+1 times.
