As answered by people managing DeveloperToolStack and ScanKeeper.
ScanKeeper's answer:
ScanKeeper is built around one insight: most people already have their codes — as plastic cards and screenshots buried in their photo gallery. ScanKeeper turns them into a wallet: it can bulk-import up to 50 screenshots at once and recognize the codes automatically. Everything works fully offline, with no account or sign-up, and the free version has no card limits.
ScanKeeper's answer:
Most loyalty card apps push accounts, offers, or subscriptions. ScanKeeper stays a simple, fast wallet: no registration, no card limits, and every feature included for free. Cards open instantly at full brightness even without signal, and bulk import from Photos means you can migrate your whole collection in a minute instead of scanning cards one by one. The only monetization is unobtrusive ads, removable with a single one-time purchase.
ScanKeeper's answer:
Everyday shoppers who carry a stack of plastic loyalty cards and keep screenshots of QR codes scattered across their photo gallery. It also fits privacy-conscious users who want an offline app with no account, and anyone organizing gym memberships, library cards, tickets, and passes in one place.
