Welcome!
From the picture I think you’d want a FlexClass, but it would probably be a good idea to try to learn some more about it first to confirm too
Are you able to scan it with your phone? You could use an app like NFC Tools or TagInfo to hopefully get some more info
It might also be worth it to check in with the guy who’d be doing the cloning, make sure he’s confident he could clone that particular credential type and all that. He might/should have the tools to double-check the chip type too
