When it becomes mandatory it would make sense for critical shops (food etc.) to be unable to refuse entry. I can see the Sunday Telegraph story now, "Pensioner couple die of starvation, unable to buy food because supermarkets refuse entry due to no phone".
Keep in mind there's an awful lot of phones out there there don't have scanning ability. Can't speak for Apple IOS but Android doesn't appear to have scanning under rev 9, which is on a lot of cheaper brands. There's also a lot of "dumb" phones still on 3G. One brand actively promoting to Seniors, simple, big buttons, no apps etc.
