Are these cards compatible with vanderbilt act 5e prox system?

Whilst I don't know for sure, as these cards are 125KHz cards and the ACT 5e system also uses 125KHz cards (and fobs), it would make sense that they would work - unless ACT have developed some special non-standard way of using these cards to force you to use theirs. We have a different system where our supplier wanted an extrotionate amount of money for cards, so we dipped our toe in by getting a 10-pack of these and they worked for us, so now we've bought a £25 pack. I'd recommend getting the smaller pack of 10 just to try them out, and maybe reply back to your own question to let others know if they worked.

Do these cards all have unique id's. are the id numbers the ones printed on the cards?

Yes they are and they all have unique id
