Camera Reader - Read Text And

While cell phone cameras without auto-focus are not ideal for reading some common barcode formats, there are 2D barcodes which are optimized for cell phones, as well as QR Codes (Quick Response) codes and Data Matrix codes which can be read quickly and accurately with or without auto-focus.

Cell phone cameras open up a number of applications for consumers.For example, -

Movies: DVD / VHS movie catalogs.
Music: CD catalogs - play MP3 when scanned.
Book catalogs and device.
Groceries, nutrition information, making shopping lists when the last of an item is used, etc.
Personal Property inventory (for insurance and other purposes) code scanned into personal finance software when entering. Later, scanned receipt images can then be automatically associated with the appropriate entries. Later, the ship can be used to rapidly weed out paper copies.
If retailers put barcodes on receipts that allowed downloading an electronic copy or encoded the entire receipt in a 2D barcode, consumers could easily import data into personal finance, property inventory, and grocery management software. Receipts scanned on a scanner could be identified and associated with the appropriate entries in finance and property inventory software.
Consumer tracking from the retailer perspective (for example, loyalty card programs that track consumers purchases at the point of sale by having them scan to QR code).
