What is QR Code Reader?
QR Code Reader is an Edge extension designed to accurately scan numerous QR- and bar-codes from your webcam or local images. It supports a variety of symbologies including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Codabar, Interleaved 2 of 5, and QR Code, making it versatile for both personal and business use. The extension houses an internal history that remembers your last 20 scans. Not relying on external services, it assures privacy as it performs all detection processes internally. Additionally, it utilizes the powerful ZBar c-library, capable of detecting multiple codes in a single frame.

This extension uses ZBar c-library, which is capable of detecting multiple QR codes and bar codes in a single frame.

What is a QR code? A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently.

What is a barcode? A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths and spacings of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons, and other geometric patterns, called matrix codes or 2D barcodes, although they do not use bars as such.

User reviews
As far as I know it works but I suggest it would be very useful to be able to paste in an image rather than needing first to save it.
