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. As long as the User never repeats a counter (and the PRF output is long enough), serial numbers should be unlikely to repeat. However, repetition becomes inevitable if the User ever “cheats” and tries to show the same credential N+1 times.
