I can tell you from first-hand experience the iFly does this for our protection. I had no idea what an iFly was when I first saw an iFly 700 on the shelf at a big Unclaimed Baggage store. Management didn't know what it was either, and it had been on their shelf quite a while so I bought it really cheap. It didn't have a data card and when I contacted iFly for an update, iFly contacted the owner of record and was not going to let me use the 700 without a copy of my legitimate receipt and the previous owner's permission. Everything worked out and I've progressed thru the 700 and 720 to the 740. Best accidental purchase I've ever made.
