The QS6500BT reads almost all 1D barcode symbologies at an extremely fast 450 scans per second while offering excellent reading performance on hard-to-read barcodes. The QS6500BT also reads most stacked 2D codes like PDF-417 and Micro PDF. This aggressive linear imaging performance is enhanced by Bluetooth cordless communication with up to a 33' range. The innovative charging-base station allows the product to scan barcodes while its lithium ion battery is charging. The base station also supports all popular host terminal interfaces and supports RSS and PDF-417 for future industry compatibility. Additionally, QS6500BT's flash memory allows for easy software upgrades.
