WalletWallet is a web-based utility designed to convert physical barcodes into functional digital passes compatible with Apple Wallet. The primary purpose is to allow users to digitize membership cards, loyalty cards, and other barcode-based items for convenient access on their Apple devices.

The tool supports various barcode formats including QR Code, Code 128, PDF417, and Aztec codes. Users can configure pass appearance with custom titles, labels, and card colors. Passes can be set with optional expiration dates (30 days, 90 days, or 365 days) to keep the Wallet tidy through auto-expiration.

The process works entirely client-side in the browser without server storage. Users can either scan barcodes using their device camera or upload images containing QR codes, with all processing happening locally. The generated passes are signed with valid Apple developer certificates to ensure proper functionality.

Benefits include eliminating the need to carry physical cards and providing quick access to digital passes. Use cases mentioned by users include creating gym passes, business cards with LinkedIn links, and rec center membership cards.

The tool targets anyone with barcode-based cards who wants to digitize them for Apple Wallet. It requires no installation or account creation, operating as a free web utility hosted on Cloudflare Workers.
