Device operation relies on several layers of security:
1) Close Proximity. A host tablet will be unsuccessful establishing a pairing with the BluePRO® device if it is not sufficiently close. In general, the host tablet must be with 2-3 meters before discovery and pairing actions can be initiated and completed. The BluePRO® device has been specifically designed to work well inside the 32feet (10m) range commonly attributed to local Bluetooth-enabled peripherals.
2) Unique Pairing. Each BluePRO® device has a unique pairing pin. To pair with the device, the tablet operator must have access to that particular device’s pairing pin. Without it, the BluePRO® device may not be paired to the host tablet.
3) Bluetooth Socket Connection. A cash drawer is an application-dependent device. Once paired, an app running on the host tablet must be ‘cash drawer aware’. The app must establish a Bluetooth socket connection to the previously-paired BluePRO® device. To complete this step, the app must possess this capability.
4) Drawer Open Command: The app must transmit the cash drawer opening command to the connected – BluePRO® device.
5) Preserved Connection: While a software connection exists, it is preserved by the BluePRO® device. No other host tablet may be introduced to interfere with the established connection.
