　　With the popularity of smart phones, especially the increasing dependence of young people on mobile phones, screen anxiety has become a problem worthy of attention. Recently, some media reported that Luke Martin, a 16-year-old Canadian boy, chose a “stupid mobile phone” with extremely limited functions, which can only make calls, send messages and view maps, so as to reduce screen time and avoid social media addiction. This behavior just caters to the rising trend of “stupid mobile phones” in Europe and America.Therefore, mobile phone lcd screen Only then will more and more pump owners cheer for it and spread the value and function of the brand. https://www.lucentparts.com/

　　Martin said that he had relied too much on social media before and was worried that he could not extricate himself from it. The “fear of missing” brought by social media made him decide to make a change. He said: “Friends who use smart phones often spend up to four or five hours in front of the screen every day. I used to do the same. Now I only use it (mobile phone) for about 20 minutes every day, which is really good. “

　　The report also pointed out that many parents also began to favor “stupid mobile phones”, not only for their children, but also for themselves and other family members. Lizzie broughton, who has a 5-year-old son, bought herself an old Nokia flip phone. She said: “This gives me the opportunity to adjust my living habits and spend more quality parent-child time with my son.” She plans to buy her son a similar mobile phone when he can use it. “It is not a good idea to let children use smartphones from the beginning.”

　　In addition to “stupid mobile phones”, some innovative products have also emerged. For example, the “unplugged” device can prevent the startup of mobile phone application software and help users control the use time. Some developers have also introduced mobile phones with monotonous operation interface and limited functions, aiming at reducing users’ screen time.

　　However, the rise of the “stupid mobile phone” trend is not easy to change people’s habit of using mobile phones for a long time. The advertising profit of social media is huge, and many enterprises may lack the motivation to push consumers to change.

　　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.

　　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.

Houston, May 15 (Reporter Xu Jianmei) The municipal authority of Galveston, an island city in eastern Texas, said on the 15th that a barge hit a local bridge that day, causing a fuel leak and damage to the bridge.

The bridge involved was the only land route to Pelican Island north of Galveston. David Flores, head of bridge affairs for the Galveston County Navigation District, said that due to strong water and high waves, a tugboat from Texas International Port lost control of two refueling barges it was driving, one of which hit the bridge pillar.

Aerial footage showed that part of the bridge pillars collapsed, and large pieces of broken concrete and rail fragments hung on one side of the bridge and fell onto the barge.

After the accident, the bridge, which was opened in 1960, was closed. Galveston City Authority said in a statement that no injuries had been reported. The accident caused a fuel leak in the Gulf of Mexico, and the U.S. Coast Guard will determine the extent of the leak and initiate control and cleanup procedures.

Galveston County spokesman Spencer Lewis said the barge could carry 30,000 gallons of oil (about 113.55 million liters). It was unclear how much leaked into the bay. About 105 kilometers of waterways around the incident were closed.

Texas A & M University at Galveston on Pelican Island said the accident caused a brief power outage at the school and power has now been restored.

According to US media reports, American ship collisions with bridges have occurred frequently in the past few months. On March 26, a container cargo ship crashed into a bridge in Baltimore, Maryland, in the eastern United States and collapsed, killing six people. On April 12 and 13 on the Ohio River near Pittsburgh, Pennsylvania, 26 inland river barges separated from their moorings due to floods and drifted uncontrollably, when one hit a bridge that had been closed. On May 9, a large barge broke loose from a tugboat on the Mississippi River flowing through Iowa and sank after hitting the nearly century-old Fort Madison Bridge.
