pos system, bluetooth connection equipment

Abstract

The invention discloses a POS system and Bluetooth connection equipment. The POS system comprises an intelligent handset or a flat computer (an intelligent host computer), a bill printer, a keyboard or a bar code scanner and the Bluetooth connection equipment, wherein the Bluetooth connection equipment is separately connected with the intelligent host computer, the bill printer, the keyboard or the bar code scanner, the Bluetooth connection equipment comprises an MCU input output module and a Bluetooth transmission module, the Bluetooth transmission module is separately connected with the intelligent host computer and the MCU input output module, the MCU input output module comprises an MCU processor and at least two USB interfaces, the MCU processor is separately connected with the USB interfaces, and the USB interfaces are connected with the bill printer, the keyboard or the bar code scanner. Through the POS system and the Bluetooth connection equipment, the intelligent host computer is made to realize communication with keyboard type equipment including the bill printer and the bar code scanner through Bluetooth connection, and a problem that the input content of input equipment such as the bar code scanner is wrongly converted by input method software of the intelligent host computer in a routine connection mode can be solved.

Description

Technical field [0001] The invention belongs to the technical field of electronic communication, and relates to a POS system, in particular to a smart POS system connected via Bluetooth; at the same time, the invention also relates to a Bluetooth connection device. Background technique [0002] 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, membership management and even cash registers. However, due to the relatively limited type and number of external interfaces of ordinary mobile phones and tablets (usually only one headphone jack and one USB charging port), it is very inconvenient to access commonly used keyboards, barcode scanners, receipt printers and other commercial peripherals. [0003] The current common practice is to buy a Bluetooth scanner and a Bluetooth printer, and establish a Bluetooth connection with the smart host respectively. The problems with thi...
