The GM65S barcode reader module features a high-performance scanning engine that can easily read various 1D barcodes and also read 2D barcodes at high speed. It boasts a very high scanning rate for linear barcodes and can easily scan both paper barcodes and barcodes on displays. The GM65S barcode reader module utilizes an intelligent image recognition algorithm and an advanced barcode decoding algorithm developed based on it. This allows for very easy and accurate barcode symbol recognition, greatly simplifying the development of barcode reading products. The GM65S is designed to meet the most demanding scanning requirements, providing consistent scanning performance in complete darkness and across a wide temperature range.
