This HAS to be a real gubbamint written memo. See if you can read this slowly without the desire to bang your head against the nearest wall:

"If the traveler does not have acceptable ID, the TCD will accept two other forms of ID "

If you accept two unacceptable IDs, does not that act make them: acceptable IDs?

2 + 2 = 5, and 2 unacceptable ID = 1 acceptable ID
