The CHECK-AT app is your digital companion for an easy verification of the new Austrian passport and ID card. With the app, check the QR code and other security features on the new passport generation easily and securely. Simple verification - without any need for technical expertise: In addition to the convenient QR code check, the CHECK-AT app guides you step by step through verifying individual security features on the new Austrian passport and ID card. Using examples, the CHECK-AT app allows you to thoroughly examine the digital and physical security features of the new passport generation and ID card – even without any special expertise. Local verification without retrieving personal data from the internet: During the QR code check, the information contained in the QR code is only displayed on the verifying device. The relevant information is directly included in the QR code and is not retrieved from a database. The app connects to the internet during the startup process to check the availability of new certificates necessary for the correct and secure verification of the QR code. If new certificates are available, the app automatically downloads them to the device in use. Furthermore, the app does not connect to the internet at any other time. No personal data is retrieved from the internet or uploaded to the internet.

About

Folo Docs

Features
Read full description

Your important documents — bills, bank statements, insurance policies, IDs, school letters — end up scattered across email, downloads and a drawer somewhere. Folo gives them one calm, private home and hands you the right one the moment you need it. Scan it, share it from any app, or forward it to your own Folo Mail address. Folo reads it on your iPhone, files it, and makes it searchable. NOTHING LAPSES QUIETLY Coming Up lists everything that expires — car registration, insurance, passport — soonest first, with a reminder two weeks ahead. ASK YOUR DOCUMENTS Ask "how much did I spend on electricity last year?" and get the answer with the documents cited. Turn it into a PDF report. FIND ANYTHING IN SECONDS Search what a document says, not its filename — "car insurance", "passport", "December payslip". SCAN, SIGN AND REDACT Capture paper with your camera, sign and fill PDFs, and black out sensitive details with true redaction — the data is removed, not just covered. PRIVATE BY DESIGN Your documents are ordinary files in your own iCloud, not on our servers. Text is read on your device, and on devices with Apple Intelligence, Folo summarises and dates new documents on your iPhone, free. Cloud AI runs only when you ask. PRICING Free to scan, import, search and organise. Folo (one-time purchase) adds signing, redaction, Folo Mail and AI with your own API key. Folo+ (subscription, 14-day free trial) adds AI with nothing to set up. One purchase covers iPhone, iPad and Mac.
