Description
Technical Field
The invention belongs to the technical field of electronic communication, and relates to a POS system, in particular to an intelligent POS system connected through Bluetooth; meanwhile, the invention also relates to Bluetooth connection equipment.
Background
With the rapid popularization of smart phones and tablet computers (smart hosts), more and more smart hosts are used as commercial terminals for sales, inventory, member management and even cash collection. However, due to the limited types and number of external interfaces (usually only one earphone hole and one USB charging port) of the general mobile phone and tablet pc, it is very inconvenient to access the commercial peripherals such as the commonly used keyboard, barcode scanning gun, and bill printer.
It is now common practice to purchase a bluetooth scan gun and a bluetooth printer, and establish a bluetooth connection with the smart host, respectively. The problems with this solution are as follows:
(1) the use is inconvenient, and the intelligent host and the two Bluetooth peripherals need to be respectively paired to establish connection;
(2) compared with common equipment, the scanning gun and the printer with the Bluetooth connection function have much higher prices;
(3) the Bluetooth scanning gun is connected to the intelligent host computer as a keyboard device, and scanning input contents are transmitted to APP application software after being converted through an input method on the host computer. This may cause the scanned content received by the APP application to be incorrect due to different input method states (for example, the input digital content may be converted into chinese or symbols by the input method and passed to the APP).
In view of the above, there is a need to design a new connection method to overcome the above-mentioned defects of the existing connection method.
