Best 5 Mobile Scanning Apps for your Phone

While we live in a world where regular businesses perform almost every process electronically, the physical printing of documents is the exception. The list gets shorter yearly - till receipts, business cards, ink-signed contracts. While the information on printed paper still exists, so does the need to scan that information into an electronic form where users can share or alter the content.
Anyone needing to scan a document must find a scanning device to perform this, either a standalone scanner or possibly integrated into a printer. As more of us work on the move and outside of an office environment, access to such scanning equipment is more challenging.
However, there is an alternative. Almost everyone now carries mobile phones with built-in cameras of sufficient resolution to provide good-quality scanning. Anyone with a suitable mobile device can scan a document anywhere with the proper scanner app.
The question is, which is the best document scanner app to use?

What to know about document scanning

A document scanner is a device that can convert a printed page into an electronic file, allowing the user to process, store, or manipulate the information in ways that aren't possible in its printed form. There are several different techniques for performing document scanning.

Flatbed scanning

Flatbed scanners position the printed page over a sheet of glass or transparent material as large as the scanned page. A light source within the scanner illuminates a point on the printed page and records how much light the page reflects from that point. The light source moves across the page from top to bottom, covering every point of the page. This action results in an electronic image of the page based on the reflected light levels.

Sheet feed scanning

Sheet feed scanners have a light source that moves from side to side in one plane. The printed document then passes the light source to scan the page from top to bottom. This type is more compact than a flatbed scanner and can process pages much quicker, though at the cost of a lower-resolution scanned image.

Portable scanning

Portable scanners operate using the same principle as sheet feed scanning, except the user must manually feed each page into the device. Their advantage is a relatively compact size relative to the equivalent sheet feed scanner.

Photo scanning

Photo scanners use digital camera technology to create an image of a page. Now that everyone routinely carries a digital camera built into their mobile devices, they have become prominent. Smartphone technology has reached the point where the phone's camera has the resolution and image quality to offer the user an effective document-scanning solution. This availability effectively replaces the need for a separate scanning device in most domestic applications.
Typical business users now only require a dedicated scanner for situations where they need to scan multiple pages routinely or need high-quality, high-resolution scanning.

What can scanning apps do?

Scanning App
Convert printed pages into digital images: The essential feature of any scanning tool is converting the printed page into a digital image of that page. The user achieves this by holding the mobile device above the page to display the area the user wishes to scan. The document scanner app should make this as simple as possible, allowing the scanning distance to be comfortable and coping with any minor movements of the hand holding the mobile device.
Built-in optical character recognition (OCR): The app should include built-in optical character recognition (OCR) technology to be helpful as a document scanner. This function will convert any recognizable text within the scanned image into characters that the user can edit within a document. Not all OCR technology is the same. Some providers perform a much better job at correctly interpreting the text, particularly where the image may suffer slight blurring or if marks on the page obscure characters.
Compare document differences: Any scanned document that uses OCR needs checking, ideally at the point of scanning when the user can compare it with the original document. This process must be straightforward and thorough to prevent the potentially grave consequences of a misidentified figure in a spreadsheet.
Identify distinct types of documents/information: A business scanner app should ideally recognize and differentiate between distinct types of scanned content. For example, if scanning a business card, the app should detect and correctly interpret phone numbers and other contact details. The app should identify the financial information and additional vital information, such as the date and VAT number, when scanning a receipt. Scanning a barcode or QR code should extract the embedded information for the code.
Easy document sharing: Once the scan and interpretation of the content are complete, the document scanner app needs to make that information available in a standard document format and accessible. This process may be saving the file to a local storage location, sharing it with an online resource, or storing it in a network location.
