Idk about this. Access control tags are hard to duplicate.. granted its possible that an ID tag could have the same numbers but it is very unlikely. Depending on the access control system and the credentials that system is using, the likelihood of getting the same ID is almost nonexistent. Unless someone is trying to hack an access control system and happens to know the numbering scheme of said system, this just sounds like a random event if it really happened.
Plus, how do we know the HTC One uses the same frequency / credential types of access control systems?
