The Key Cards app is a digital wallet application designed to store and manage all your cards - from membership and rewards cards to important identification cards like your driver’s license and insurance cards. Simply take a photo of your card and assign a label to it, and then the app will securely store the image in an organized, easy-to-navigate interface. When needed, you can easily pull up the image of the card for showing or scanning. The Key Cards app keeps your card images separate from your personal photos and photo gallery. The cards are only stored on your device (not the cloud) and can only be accessed by you. If you're tired of carrying around a bulky wallet or fumbling through dozens of cards at the checkout counter, this app will make your life much easier. Everything you need is right on your phone. We hope that the Key Cards app will become one of your favorite everyday apps.

Scan a page, sign it and send a clean PDF. Your documents stay on your device, never on a server. No account. No ads. Point the camera and ScanOnce does the rest. Available in English, Spanish, French, German, Arabic, Russian, Hindi, Ukrainian, Korean, Portuguese, Simplified and Traditional Chinese, Japanese and Indonesian. WHAT IT DOES Sharp, automatic captures Point the camera at a page. Edges are detected, the page is straightened, and multi-page documents are captured in one go. Search inside every scan Text is recognized directly on your device, so you can search for a word you remember and land on the right page. Read, titled and filed for you ScanOnce reads each document on the device, gives it a clear title and files it with others of the same kind. Export the way you need Share as PDF, export pages as JPEG, or send straight to a printer. Tidy it up Switch between colour, greyscale, black and white and photo filters. Reorder pages, rename documents and keep them in folders. Business cards to Contacts Scan a card and save the details straight to Contacts. Locked if you want it locked Turn on Face ID and your documents stay sealed behind it. PRO The free library holds 3 documents. Pro adds: Sign and fill Draw your signature with your finger, place it on any page and write in dates and details by hand. It all goes into the PDF. Unlimited documents Keep every scan, however many there are. Receipts to a spreadsheet Turn your receipts and invoices into a CSV spreadsheet for expenses. Clean exports Free exports from 4.2 carry a small “Scanned with ScanOnce” line at the foot of each page. Pro removes it. If you had ScanOnce before 4.2, your exports stay clean and nothing changes for you. PRIVACY, PLAINLY Your documents, their text and your PDFs never leave this device unless you share them yourself. There is no account, no advertising and no tracking. ScanOnce goes online for two things only: purchases, which Apple handles, and, on installs from 4.2, sending anonymous usage counts such as “a scan was saved”. Those counts carry no identifier and nothing from your pages. If you delete the app, your documents go with it. PLANS AND TERMS Pro comes as an auto-renewing monthly or yearly subscription, each with a 7-day free trial, or as a one-time payment. Payment is charged to your Apple Account. A subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it anytime in your Apple Account settings.
