RFID checkout at Uniqlo‘s Fifth Avenue flagship store has New Yorkers calling it magical – no need to scan products one-by-one. Just toss items into the payment box, and the system automatically lists all products and prices. A quick card swipe completes your seamless payment.
Hassan Khan, a doctoral candidate in semiconductor policy, admits that he was quite shocked when he first experienced the self-checkout service.
What surprises Khan even more is that the technology behind this “silky smoothness” is RFID, which is “not much more advanced than scanning bar codes.
RFID full name “radio frequency identification (Radio-frequency identification)”, it is a kind of wireless communication technology, can through the radio signal identification of specific targets and read and write relevant data.
The earliest application of this technology can be traced back to World War II, when the Royal Air Force used it to identify fighter planes as friend or foe.
Now, decades later, this ‘old’ technology has the potential to make people feel the charm of technology’s high level of simplicity, and has become an important part of digitization that many retailers value.
1. The RFID that makes self-checkout less obnoxious

The typical self-checkout system takes the work of a paid employee and transfers it to an unpaid customer. It changes the person doing the labor, but those labors haven’t changed at all.
Ben Cohen, a columnist for the Wall Street Journal, commented.
From my point of view, the labor of swiping the code one item at a time is barely acceptable, but the point is that the checkout system can always be buggy in various ways, so that you have to alert the salesperson to solve the bug, which is annoying.
In the early days of supermarkets, when you scanned a duplicate product, you had to ask the clerk to bring in a special code in order to cancel the product; in the existing convenience stores, you have to look for the relevant product page to buy coffee and buns without barcode.
In the small red book, there are also many people reflected obviously have been very careful, self-checkout still will miss the scan or more scanning products, either accidentally become “theft”, or give more money.
Recently, the U.S. chain store Target also announced a reduction in the opening hours of the self-checkout machine, due to the seriousness of the theft of goods.
In the U.S. Walmart, store employees also have the right to temporarily close the self-service lanes to check out customers if they suspect they have merchandise that has not yet been checked out. At Walmart in China, we can also see that there is always a clerk watching by the self-checkout.
All in all, the experience is hard to say.
That’s why Uniqlo’s self-checkout looks ‘amazing’ in comparison.
RFID consists of two main things: an RFID tag and a decoder. When the RFID is within the effective range of the decoder, the two can exchange information.
Uniqlo implanted RFID tags on the clothes tags, when the consumer puts the clothes into the checkout box equipped with a decoder, the system will be able to read the information, automatically calculate the number of products, out of the bill, saving the trouble of scanning the code.
Since the introduction of this system, the waiting time for consumers to pay has been directly reduced by half, according to the Xunmai Group.
Also, the process of putting clothes in the checkout box and then counting the items while seemingly ‘nothing happens’ adds a ‘magical’ element to the experience.
We wanted to bring in the ‘wow’ factor – it’s not just about buying an item and paying for it.
It’s not just about buying a product and paying for it,” explains Takahiro Tambara, CIO of Uniqlo’s parent company, the Xunxo Group.
The design, which in retrospect feels like “the way it should be,” has actually gone through iterations.
When it was first introduced in 2014, the checkout box actually had a cover that had to be closed after the user put in the clothes before the decoder could read the RFID tag information.
Tambara realized that this design wasn’t convenient for users and that “it didn’t enhance user service,” before replacing it to the current model in 2019.
In addition to Uniqlo, Zara and Decathlon have also adopted RFID-based self-checkout systems.
2. So why don’t supermarkets use this model?
Unlike the brands listed above, which are “self-produced” and can be tagged from upstream, Walmart brings together a large number of brands with a large volume of products.
Although the cost of RFID tags has fallen dramatically in recent years, from 15 cents per tag in 2007 to about 4 cents per tag now, but if the supermarkets have to add additional RFID tags for each product, the cost is not low.
However, how the future is not easy to say, even Amazon last year also began to incorporate RFID into the offline payment technology system.
At the beginning, Amazon unmanned supermarket launched the “Just Walk Out (take after walking)” system, which allows users to register and bind a good account, enter the store to choose the goods and then go directly.
The “checkout” is no longer a task that requires the active participation of the user, but is completed by automatic deduction directly on the bound account.
However, the system behind this relies mainly on computer vision technology, requiring stores to configure a large number of sensors and cameras, combined with deep learning to support operation.
In other words, the cost is high, and there is a threshold for trying to promote it.
Last September, Amazon began to launch the RFID version of the “Just Walk Out” technology, directly on the product listing plus RFID tags, leaving the field through a space with a decoder can be calculated.
So who knows if supermarkets will be using RFID in the future?
Snipes, an e-commerce platform for footwear, says that 70% of its products are now RFID-tagged. That number will continue to grow in the future.
Moreover, the role of RFID checkout is far more than just checking out, it is the key to make items become real-time visible “live data”.
3.The Low-Tech of Turning Items into “Live Data”
We didn’t introduce RFID because we wanted to automate the payment process. What we wanted to do was build a platform that encompassed the entire supply chain,” Tambara explains.
We wanted to build a platform that encompassed the entire supply chain,” Tambara explains.
Since 2017, all of Xunmao’s brands have been using RFID tags, allowing the group to track each individual product all the way from the factory, to the warehouse, to the store.
In other words, a small RFID tag can turn an item into “live data”, so you don’t have to rely on the human eye to track or find it, you can just turn on the system and see its status.
This data directly helps Zara sell more products at regular prices.
For example, if a product doesn’t sell well in a particular store, and the system has timely feedback, Zara will put the inventory online and try to sell the item at the regular price, reducing the number of items that go into a price reduction period.
In addition, such real-time data also makes ‘buy online, pick up offline’ possible.
When we shop online, we can synchronize our shopping with the stores that still have stock.
In some of Victoria’s stores, users in the fitting room can also use the RFID tags on the clothes to view more colors and sizes of the product on the smart device, and let the store staff send it to the fitting room if needed.
For some brands, RFID data is even more important to ensure that products are “seen” by customers – avoiding sold-out shelves or missed sales opportunities due to theft or misplaced items that can’t be found by consumers.
Outside of the apparel industry, McDonald’s is one of the companies that has experimented a lot with RFID.
Have you tried McDonald’s table service?
Have you ever tried McDonald’s table delivery service? Have you ever carefully placed a numbered sign in a conspicuous place so that the clerk can easily find you?
In fact, these signs aren’t just signs, they’ll use Bluetooth or RFID technology (which varies from regional market to regional market) to help the clerk see where you are.
Starting last year, McDonald’s, in order to comply with new French regulations governing disposable food and beverage containers, (very reluctantly) replaced the containers used to hold fries, burgers, chicken nuggets, and cups used to serve in-store meals with reusable plastic versions that are also fitted with RFID tags.
In this way, McDonald’s will not only be able to track how many times these products have been recycled, but also be able to detect when consumers accidentally throw them into the regular trash can by mistake.
In life, RFID can be found in the access cards we all use every day, the ETC on the way home, or in the self-checkout/return machines at the library.
New technology is always exciting, but perhaps we’ll have to wait for this new technology to sink from identifying warplanes to tracking a plastic box used to hold French fries before we can see how much potential it really has.
