The supermarket is going to stick with their electronic shelf labels as they are wireless updating, so no need for pulling them off the shelf to run through a printer. There will be other niches though, one mentioned is public transport e-money/fare cards having the fare updated and promotional advertising. I can't see that happening though as this would be too slow to move through a gate compared to a NFC card. From a transport operators point of view they are unlikely to want move back towards a system where the fare gate ingests, prints and ejects a card. Have you seen the inside of a fare gate for dealing with magnetic cards? More mechanical parts than your average pinball machine, a wonder of technology but really nowhere near as reliable as an NFC reader (picture at http://www.industrytap.com/japan-railways-automated-ticket-gates-named-ieee-milestone/10930 http://www.industrytap.com/japan-railways-automated-ticket-g... and illustrative video at https://youtu.be/MIzekUVPdgY https://youtu.be/MIzekUVPdgY). And of course NFC is getting more availability on mobile phones so the fare card will disappear into the mobile. And of course, there is paper, mighty cheap and comes in fancy colours :) Edited - add ticket gate image and video
