Analyse de l'application StampJar pour le 5 octobre

Replace paper punch cards with loyalty cards customers can keep as a picture or PDF. StampJar runs entirely from your shop's iPhone or iPad: issue a signed QR card, scan it at the counter and keep every stamp and reward in a local ledger. Customers do not install an app, create an account or provide an email address. You hand over the card through Messages, AirDrop, email or print, using the sharing options already on your device. Built for the counter • Start a new card in seconds • Scan the card's QR code or enter its six-character code • Add stamps, correct the latest stamp and record rewards • Search active and retired cards • See daily activity and reward counts Make it yours • Set your shop name, reward and stamp threshold • Choose a card palette, logo, stamp mark, tagline and terms • Preview exactly what the customer receives • Share a PNG or print-ready PDF Private by design • No account, cloud sync, backend, analytics, ads or tracking • Card and stamp data stays on your device • Customer names and phone numbers are optional and off by default • Optional contact details are never drawn on customer cards • Export your ledger as CSV whenever you choose A card is sent once and stays useful: its QR identifies the card, while the current stamp count stays in the shop's ledger, where it is always up to date.
