People's Congress can use RFID technology, "brush plate" three seconds checkout

On September 4th, the restaurant on the first floor of the dining hall in the North District of Renmin University of China launched a smart settlement service. After the students selected the dishes in the self-service area, they placed the plates in the “settlement area”, and the checkout counter would measure the price of the chips brought by different tableware. The automatic generation of the total price, students can leave after swiping the card, the whole process takes only three seconds, which avoids the situation that students have spent a lot of time queuing for dinner. The Beijing Youth Daily reporter learned that at present, many universities in and outside Beijing have begun to implement this intelligent settlement mode.

On-site "brushing" settlement takes only three seconds

At 4:30 pm on the same day, there was no longer a meal. There was a long queue outside the smart restaurant on the first floor of the dining hall in the North District of the National People's Congress. Many students wanted to experience a smart settlement of "black technology" and make "the first one." The person who eats crabs."

"One or two rice, 0.25 yuan; garlic yellow scrambled eggs 5 yuan; tomato egg soup, 1 yuan; fried Chinese cabbage 2 yuan", at the exit of the smart restaurant, Beijing Youth Daily reporter saw that the students have a meal The tray is placed in the “settlement area” box. The name and price of the dish are displayed in the sixteen squares on the left side of the desktop screen, and the quantity, total price, nutrient composition, and card balance are displayed on the right side.

Corresponding to the checkout desk screen is a vertical screen with a 45-degree angle and a 15-inch width, which is set for the staff. This structure is very similar to the supermarket counter, but the difference is that the settlement here is automatic, no need to scan the code gun. It takes only three seconds from placing the pallet in the settlement area to swiping the card to the end of the pallet.

According to Wang Haorong, director of the North District canteen, the dishes in the smart restaurant are all embedded with RFID radio frequency chips, and the chip can repeatedly write food information through the production terminal. After the tableware is placed in the settlement area (RF antenna sensing area), the computer will automatically read and write the chip, and use modern communication technology to achieve fast settlement.

Extending "black technology" big data can determine the replacement of dishes

In addition to reducing queues and improving settlement efficiency, the “black technology” of smart settlement can also provide students with big food data for eating in the cafeteria.

After the trial operation of the NPC Wisdom Restaurant, students have posted messages on the school Weibo and WeChat, hoping that the “Nutrition Table” will help them “burn” their calories. According to Song Da, general manager of the logistics group, the next step is to cooperate with the school business school and the school of statistics to understand the consumption propensity of students through big data and help students to establish healthier eating habits. By launching a diet health app, students are connected to other sports and fitness apps to remind them to take calories properly.

For the director of the North District canteen, Wang Rongrong, this big data also made him "save a lot of things". In the past, the preferences of the students' tastes needed to be sent out to investigate. Now, the students’ credit card data is clear. . “Big data can completely determine the innovation of dishes.” Wang Rongrong said that students can buy “less dishes” directly and “off the shelf”. At the same time, this big data also provides an important basis for the management of the kitchen. “The dishes that the chefs made every day. How many copies are sold is difficult to calculate", and the current selling data can be used as a performance appraisal standard.
