true but I'm guessing that if using the app to checkin is something the OPs mother might not be familiar with I'd guess that the iOS wallet might also be something they would struggle with. Using the kiosks to reprint is likely the best option, an MMS of the mobile BP as a backup and/or to scan at the kiosk gives two easy options for those that are less technology enabled
