We found the LaserMagic Bluetooth scanner with SerialMagic which met these requirements

We are a relatively small bookstore in a French Canadian environment where we sell on site and we go to shows where we needed flexible barcode scanning to easily establish the prices when a crowd is hanging around. Also we wanted to accelerate the inventoring process. As our inventory system is based on Linux and PostgresSQL the scanner and the software should support this environment. For flexibilty we needed of course Bluetooth. We found the LaserMagic Bluetooth scanner with SerialMagic which met these requirements. The price was right and the hardware and software work to full satisfaction.
