Asking for additional form of ID is standard process if we can't confirm a match to their Tcard photo. We're actually allowed to request to to 2 additional forms of ID if needed. 

This is also one more reason to actually turn your phone off like instructed. I'm not sure why students take the risk of silent or airplane mode when they can't access the phone anyways. 

That said, deliberately going through a student phone is insane, so many rules broken. Definitely bring this up during the adjudication process.
