Recently, I went shopping with my friends and walked into a clothing store. The venue was not big, but the facilities were fully charged. I used the cash register system. I learned from the boss that he made a simple, cheap and convenient cashier in order to manage the inventory. system. Looking at his entire process, he couldn't believe the system was so cheap. So I sat down and listened to him saying the source of the simplest cash register pos system: So only need to prepare two things: mobile phone and Bluetooth printer. Apple and Android phones can be used, Bluetooth printers choose Jiabo GP-58MBIII, Jiabo printer is still a good drop. Next, The first step: download the appropriate APP. I have downloaded a lot of these apps, including business experts, thinkers, shop assistants, Qinsi business, and so on. Finally, it is found that business experts are easy to use, do not need to spend money, have a free version, easy to operate, do not mind, can scan the label bar code, the most important thing is that the free version can print. Other apps are not suitable. Like the thinker of Skytron, you need to create background data on the computer. The mobile app is just an aid and may be suitable for large stores. Qin silk business pass, won't use for a long time, and the free version does not support printing. Step 2: Prepare the Bluetooth printer. Recommended GP-58MBIII Bluetooth version, as shown in the figure, if you need portable mobile, buy a GP-PT260 Bluetooth printer. It is worth noting that when buying, you must ask the seller whether Bluetooth supports 1 to 8 and can support 1 Apple app and 7 Android apps to connect to the printer. Explain: According to the Bluetooth standard protocol, a Bluetooth device can only be connected by one Bluetooth host. That is, a Bluetooth printer can only be connected by one mobile phone, and can only be connected by one APP in the mobile phone. But now many take-away merchants have a lot of apps installed in their mobile phones, such as hungry, Meituan, Jingdong, etc. If you are hungry and connected to a Bluetooth printer, then the US Mission and JD.com can’t connect, need to be hungry, disconnect the Bluetooth connection. Other apps can connect. Later, in order to meet the application scenarios of multiple mobile phones or multiple APPs simultaneously using the printer, the Chinese developers were imaginative and modified the Bluetooth protocol, and the 1 to 8 Bluetooth module appeared. Support multiple phones and multiple apps to connect at the same time. The fourth step: the cash register, print the small ticket. Install the GP-58MBIII paper, the power is turned on, and the blue light is on, it means normal. After clicking the cash register on the APP, after selecting the goods or filling in the amount, click the checkout -> Confirm -> Print the ticket. Go to the print ticket interface and click Search Bluetooth in the upper right corner. If the printer is turned on normally, a device with the device name (Gprinter_number format) will appear in the searched device. This is our Bluetooth printer. Click here. After the device prompts that the connection is successful, the device will appear in the connected device, check the device, and click the print ticket, as shown in the figure. The device name can be viewed on the printer's self-test page. As shown in the figure, the different machine names are the same, and the next four letters are different. Jiabo printer prints self-test page: Shut down, press and hold the FEED button, and then turn it on, it will release the hand after about 2 seconds. If the operation is successful, the self-test strip will be printed. You're done, the print effect is shown in the picture. Unfortunately, the two lines below the free version of the cashier expert can't be removed. The paid version can be removed, and the print format can be customized.

He first asked a friend to understand the demand analysis: In fact, the clothing store business is very simple, as long as the inventory management, customer management, cash register accounting, print ticket function can be achieved. Coupled with limited space, if you buy a pos machine, the first place is no place, the second waste, the third expensive. What the computer can do, now both the phone and the tablet can do it, and the smartphone uses the existing one. To achieve cashier accounting, print a small ticket, buy a Bluetooth printer. 
The third step: commodity and membership management. After the APP is simply registered, you can perform brainless operations, add items, add members, and be physically fit. Follow the prompts to record your clothes.
