GM805 barcode reading module is a GM80X series integrated small product, which has two interfaces: row-inserting and horizontal-inserting, and can be directly output, which is convenient for users to develop and apply. Adhering to the excellent scanning engine of GM80X series products, it can not only easily read all kinds of one-dimensional barcodes, but also read two-dimensional barcodes at high speed, with a very high scanning rate for linear barcodes, and can also easily scan paper barcodes and barcodes on display screens.
