Hmm… from what I am seeing, the TEMIC card is actually a T5577 re-programmable card… so it’s based on the same chip that the xEM is. I’d say it’s compatible… just not sure what would be required to clone a TEMIC card to an xEM… but if the antenna on the programmer at the hotel was compatible, I’m sure it could be written to… just be careful though, most programmers/cloners set a password too.
