Ok I understand now. The hold-up on the legality of these documents has always been the customs and immigration people. The faxed receipts were a problem with the border people when they first came out also and many people had trouble until Canada Customs and INS people got acquainted with e-tix.

I was wondering since I have to turn the laptop on a Security, if now I also have to switch it on at checkin and at the bording point just to show the receipt .
