Keep important cards and document copies close at hand in a private wallet on your iPhone. Scan the front and back of a card, search your saved cards offline, and choose which details to show for each situation. PRIVACY BY DESIGN • Your wallet is encrypted on your iPhone and protected by device authentication. • Hide selected details while keeping your original images unchanged. • Create reusable Ways to Present and preview them before sharing. • Core wallet use does not require a digiID account. MORE THAN ID CARDS Organize membership cards, business cards, passport copies, certificates and other personal documents. Use favorites, categories and expiry reminders to find what you need. PRESENT WITH CONTROL Open a focused full-screen view, switch between front and back, and zoom to inspect details. Rotate your iPhone for landscape presentation. Review both sides before showing or exporting a copy. START WITH ONE FREE CARD Your first saved card is free. Basic privacy editing, barcode and QR-code checks, access to saved cards, recovery and plain privacy-masked PDF export remain available without a subscription. Detection can miss details or codes, so always review the result. OPTIONAL DIGIID PLUS Add more cards and save up to 50 Ways to Present per card. Choose Prism, Aurora, Gold or Graphite privacy finishes. Add purpose, recipient and date labels to PDF copies. Use Home Screen and Lock Screen widgets and create a portrait image for an Apple Shortcuts Home Screen launcher. The U.S. offer is three months free for eligible subscribers, then $0.99 per month. Prices vary by storefront; the App Store displays your local price and eligibility. Payment is charged to your Apple Account. The subscription automatically renews unless canceled. Manage or cancel through your Apple Account subscription settings. ALREADY PURCHASED THE ORIGINAL UNLOCK? Your original Limited purchase remains separate and retains its purchased card and saved-version capacity. Restore it with the Apple Account that made the original purchase. Ending Plus does not delete your cards, remove saved privacy masks or disable existing saved presentation versions. Compatible cards from earlier digiID Limited versions can be recovered on the same device while their original files remain available. Do not delete the app before updating. digiID stores personal copies for convenience. It does not issue, verify, replace or authenticate official identification. Acceptance is up to the recipient. Holograms are decorative privacy covers, not issuer security marks. Purpose labels do not prevent copying. Portrait shortcuts do not replace the installed app icon.
