ScanFolio Support

Updated: 6 October 2026

For help with ScanFolio, email appdev@i3hk.net. Tell us what happened and, if possible, include your device model and iOS version. Please avoid sending passport details, boarding-pass codes, or other sensitive scan content.

Basic and Plus

Basic includes live barcode scanning, raw results, opening link results with GO, and creating a basic QR preview from text. Plus unlocks live MRZ recognition, text recognition after Capture or photo import, other generation formats and settings, Save to Photos, saving to History, encrypted iCloud sync, sharing and parsed travel-document details.

An active Plus subscription is required to access History. If Plus expires, saved scans are retained, but History stays locked until Plus is active again.

Common questions

The camera is unavailable. Camera scanning requires a supported device with a camera; the iOS simulator has no live camera feed. On your device, open Settings → Privacy & Security → Camera and make sure ScanFolio has permission to use the camera.

A code or document is not recognized. Try better lighting, hold the camera steady, reduce glare, or use a clearer photo. Results depend on image quality and device support. ScanFolio reads information; it does not confirm that a document or ticket is valid.

My saved scans are missing on another device. Check that Plus is active and unlock History on both devices. Make sure both devices use the same Apple account and have iCloud and iCloud Keychain enabled. Sync may take time. Open History and pull down to refresh. A scan cannot be shown on the other device until its encryption key has synced.

How do I delete a scan? In History, swipe left on the scan and tap Delete. You can also open it and tap Delete scan. If iCloud sync is active, the deletion will reach your other devices after they sync.

How do I delete all scans? Open History, tap Delete all scans, and confirm. Separately saved Photos images and copies shared outside the app are not removed.

An older saved image is missing. Open its History detail and tap Download photo from iCloud. Images from the last two days download automatically when available; older images download on request. iCloud must be available.

History will not unlock. History uses iOS device-owner authentication: Face ID, Touch ID where available, or your device passcode. Make sure a device passcode is configured, then try unlocking again. History locks when the app enters the background.

How do I save a generated image? With Plus, generate a valid code, then tap Save to Photos and allow photo-library additions. ScanFolio saves the generated PNG; it does not need access to your entire photo library for this action.

A generated code is not accepted by a reader. Check the input and chosen format, keep the white border visible, and try a larger display size. Some formats and settings need a compatible reader; Code 39 Full ASCII needs matching reader configuration. A generated code does not assign a retail product number, issue a ticket, or verify the encoded information.

Can ScanFolio read a passport chip or validate a boarding pass? NFC/ePassport chip reading is unavailable. MRZ check digits and boarding-pass field parsing are local checks; they do not establish authenticity, identity or ticket validity.

My ScanFolio Plus subscription is not showing. Open the Plus screen and tap Restore purchases. To change or cancel your subscription, open Settings → [your name] → Subscriptions on your device.
