The wallet is designed as a voluntary option, so anyone who would rather keep things analogue can stick with the plastic card. The EU requires national wallets to be recognised by other member states, so in principle the same app should get you through an ID check in Sicily just as it would in Sliema. If banks, payment apps and licensed operators all plug in, the ID selfie could quietly disappear. If they do not, you will have a shiny new wallet on your phone and still be photographing the back of your ID card in the kitchen.
