Power Scan - Barcode Scanner is a free tool, which allows users to scan barcodes and QR codes. After scanning a barcode, the application will display various matching results, allowing for price comparisons to be performed quickly. The app supports scanning for UPC-A, UPC-E, EAN-13, EAN-8 and ISBN barcodes, and these codes can be scanned through a camera, or entered manually. However, there is a limit on the number of scans that can be performed and an upgrade to the paid version is required for users who wish to exceed this limit.
