The Manhattan 2D Barcode Scanner offers a scan rate of 300 scans per second and an accurate read range of up to 21.65 in. The 2D scan engine offers speed, accuracy and greater tolerances for reliable service as it reads popular 1D and 2D barcodes, including UPC/EAN, UCC/EAN128, Data Matrix, PDF 417, Maxicode and more. Easy to implement and simple to use, a built-in keyboard wedge decoder sends scanned data to an active application where it appears as if it were manually typed or directly keyed into the computer. Its versatile USB interface and bus power integrate with most PCs without the need for an external power supply or complicated installation. 3 Year Warranty"
