CHALLENGES• Reduce Time Customer
Spends at Checkout• Increase Accuracy of Items atCheckout• Enable a Wider Range of Items(including weight)

While self-checkout at many customers' grocery and convenience stores is
implemented worldwide, there are faster and more accurate technologies that canenhance the customer experience. There are many thousands of establishments where
the current self-checkout systems can be improved, reducing time for customers andincreasing product identification, which results in a smoother and more customerfriendly environment. Using Artificial Intelligence (AI) to identify the item being
purchased, an accurate list of these items can be determined for billing purposes.
Scanning an entire basket or cart of items can easily lead to intended or unintended
mistakes and a slow checkout line, as each item must be scanned individually.

Challenges
While self-checkout has been in use for a few years, new technologies are becoming
available that enhance the ability of customers to get through the process quicker thanever before. The UST Vision Checkout system was designed from the ground up toaccelerate the customer experience while reducing mistakes and time consuming tasks.
In some environments, the item is not packaged but plated, for example, in a cafeteriastyle setting. In this case, the system needs to identify the food and quantity before
determining the price to charge. In a grocery store, touchless checking of produce(irregular shape), for example, will be much more accurate than a consumer typing in a
product code.
The UST Vision Checkout system needed powerful servers that live at the "edge" of thenetwork. These systems needed to be compact and contain the necessary CPUs and© Copyright 2023 SupermicroGPUs to create a checkout system where the computer was not a bottleneck. Besides
the basic hardware, the UST Vision Checkout System needed to be expandable so thatthe same server could be used in different scenarios, depending on the customer traffic.
Keeping the same basic server system but increasing the number of GPUs reduces costs,
as the same system is used for different scenarios.
UST needed to use a server with a fast processor that could also house multiple GPUs
and communicate with other systems seamlessly. While the customer experiences the"inferencing" during checkout, UST needed a server for the training system. For
simplicity, UST wanted the same servers to be able to be "trained" and then used for theactual checkout experience.

Supermicro Edge Server

Experience the future of shopping with UST Vision Checkout! Say goodbye to longqueues and tedious checkout processes. With Supermicro, Intel, and UST cutting-edge
technology, you can breeze through the checkout in seconds. UST Technologies
determined that the Supermicro E403 SuperServer would be ideal for this application.
The Supermicro SYS-E403-12P-FN2T is a powerful server with an Intel® Xeon Gold 4310
and 64GB of memory.

During the training phase, an item is placed in a product-training box, and a 360-degreescan of the product is performed. Within 5 minutes, the scans from the image and otheridentifying information such as the UPC, current pricing, and additional identifying
information are saved.

UST was able to quickly design, implement, and test a kiosk that used the Supermicro
E403 containing one, two, or three Intel Data GPU Flex 170 series cards. One of thissystem's most critical aspects was measuring the accuracy and speed of the solution.
During a pilot phase, where strict requirements were set, the checkout solution
identified all products in five seconds or less, with 95 percent accuracy. The rapid,
accurate response was supported by a unique product-training box (shown above ),where venue managers scan each stock-keeping unit (SKU) from all sides on a rotating
platform surrounded by cameras. The 360-degree scans form a complete reference
image and are stored for on-demand transmission to the UST Vision Checkout kiosk,along with unit pricing, a UPC, and other identifying information for each SKU. The
comprehensive product data can also be integrated with inventory management andplanning solutions at the store or chain level.

scanning, where the shopper must first locate the UPC, align it to the scanner and thenplace the item on another platform for weighing and verification purposes.
