A printed card has two problems. Most of them end up in a bin within a day, and the moment one detail changes — a number, an address, a new Instagram — the whole box is wasted. A Tapify card is handed over, tapped, and your details are saved on their phone before you have finished the sentence. Nothing to install, nothing to scan if the phone supports NFC, and a QR code on the back for the ones that do not. And because your details live on a profile rather than on the card, you change them once and every card already in circulation updates itself.
