The Ingenico Dual Runners Laser RFID reader has an intuitive user interface, using the same button to switch it on, connect and scan data. A multi color LED display shows the connection and battery status while audible beeps indicate successful scans. When the Ingenico Dual Runners Laser is connected to a host, scanned data is transmitted in real time to that host. Bar codes are stored in internal memory until they are acknowledged by the application. If you scan data out of the radio range, they will be stored in memory and automatically downloaded when getting back into range.
