　　The cash register is the starting point of payment in the entire payment transaction system. What is its status in the physical terminal, and how is it integrated with the cash register software system?

　　1. Classification of all-in-one machines

　　Classification by system: Cash registers are divided into: WPOS (Windows POS), MPOS (mobile POS) according to the installation system environment. Among them, the popular MPOS on the market is mainly Android POS (APOS). WPOS has high price, high configuration, and convenient switching of cash register software. MPOS is mainly about APOS here. Low price, low configuration, software is usually factory set, and cash register software cannot be changed later.

　　2. Classification by scenario

　　Desktop cash register: The cash register is placed on the desktop, with single-screen touch screen and dual-screen touch screen cash registers. It can be connected to external face scanning devices, palm scanning devices, barcode scanning guns, etc. Face scanning devices are also embedded in the cash register.

　　Desktop cash register: The cash register is placed on the desktop, with single-screen touch screen and dual-screen touch screen cash registers. It can be connected to external face scanning devices, palm scanning devices, barcode scanning guns, etc. Face recognition devices are also built into cash registers.

　　Unmanned cash registers: Unmanned cash registers are used in unmanned retail scenarios. Usually, this equipment is installed in subway stations, hospitals, and office spaces. Merchants place unmanned cash registers in these places and update products regularly. There is no need for people to be on duty on site, and goods are sold automatically.

　　3. What problems are solved?

　　The ultimate goal of the cash register is to improve cash register efficiency and operate stores digitally. Let’s analyze from the perspective of merchants and customers. What changes have the cash register brought to both parties? What specific problems has it solved?

　　From the perspective of merchants: mainly from the dimensions of financial management and inventory management. As an offline terminal, the cash register can be used as a data information collector for the daily operation of merchants. When customers purchase goods or services offline, the cashier will generate a pending order after selecting the product and placing an order on the cash register, waiting for the customer to pay successfully. The cash register system will update the payment order status, generate a flow, and automatically deduct the inventory of the goods. The original data submitted by the cash register obtained by the merchant backend will display data reports according to different dimensions. Merchants can use mobile apps and backend systems to keep track of the actual store operating data and changes in store inventory in real time.

　　From the customer’s perspective: mainly analyze from the perspective of payment fluency and the experience of the cashier process. When customers check out: customers use many payment methods, but merchants do not support them; the checkout queue is endless; it is impossible to understand the product information and promotional prices… These problems may make customers leave. POS cash registers can solve the above problems: POS cash registers can support multiple payment methods, and the system automatically obtains promotional information prices after the product is entered into the system, thereby improving cashier efficiency.

According to the Associated Press reported on March 17, U.S. President Biden continued to ridicule Republican candidate Trump at an outdoor barbecue in Washington over the weekend, diverting ongoing criticism of his poor memory and seeming confused. He emphasized that 77-year-old Trump also makes mistakes.

Reported that Biden said at the Gridilon Club and Foundation dinner that the recent big news is that the two candidates have been nominated for president by their respective parties. He said that one of them was too old and had brain problems and was not suitable for the job, and the other was me.

Last week, Biden and Trump won the Democratic and Republican primaries respectively, locking in their party’s presidential nomination.

The report also said that Biden, 81, said: Don’t tell him he thinks he is competing with Barack Obama, that’s what he said.

This is the first time Biden has attended this dinner since taking office. The 2024 U.S. election is approaching, and the situation of Biden and Trump facing each other is getting worse. (Compiled by Yang Xinpeng)

Seoul, March 18 (Reporters Lu Rui and Sun Yiran) The so-called Third Democracy Summit led by the United States was held in Seoul, South Korea from the 18th to the 20th. South Korean citizen groups held a rally in central Seoul on the 18th to protest the so-called democracy summit.

According to local media reports, South Korean citizens ‘group National Popular Action held a press conference near the venue of the Democracy Summit on the same day to express their protest. People held banners that opposed the democracy summit held to maintain U.S. hegemony, and shouted slogans such as the democracy summit spreading false democracy and condemning Yin Yue’s government for blindly following the U.S. -centered value alliance.

Some rally participants said that the United States decided to hold the democracy summit in South Korea. Its intention was very obvious, to maintain its hegemony that was gradually collapsing and push South Korea to the front line of camp confrontation.

South Korea’s “Jingxiang Shimbun” published a commentary on the 17th, saying that the so-called democracy summit with the logic of camp confrontation does not have much support around the world, but South Korea has taken the lead in promoting the new Cold War values of the United States. Whether such an approach will help South Korea’s national interests is questionable.

Under the banner of democracy, the United States held the so-called democracy summit via video in December 2021 and a combination of online and offline in March 2023, which have been widely questioned by the international community.
