Scanner App:PDF Documents Scan

Passports and ID cards are awkward to scan well, and this iPhone scanner from WICRO Technology makes a point of having modes for them. The rest of its scope is everyday paperwork: receipts, invoices, contracts, notes and pages from books, turned into PDFs or images.

Automatic edge detection and cropping frame the page, with tools to straighten, rotate and reduce shadows, and save the result untouched, cleaned up, in grayscale, or as pure black and white. Documents can run to multiple pages, a hand-drawn signature can be placed on a scan before sending, files go out by email, and a history keeps earlier scans. A subscription that renews automatically covers the premium features.

Renewing a visa or opening a bank account means photographing a passport, and that is where the dedicated mode earns its keep, framing the document and flattening the glare. On a normal day it's receipts and invoices: scan, remove the shadow your hand cast, pick black and white, and email it off. A contract that needs a signature gets one drawn with a finger and dropped onto the page before it goes. The history list is the fallback when you need last month's invoice again.

ID and passport scanning is the specific search, often from people filling in an online application that demands a clean image of their documents. Shadow removal is the second draw, because phone scans of paper on a desk nearly always have one. Beyond that it competes with every other PDF scanner for the receipt-and-invoice crowd.

Three screenshots only, which leaves much of the interface to the imagination. They probably cover the camera view with document framing, an edit screen with the filter options and the ID or passport mode. Tools-category scanners usually use a neutral palette with a brightly coloured capture button, but the listing doesn't say so, and nothing confirms how the signature tool looks.
