In an age where speed defines success, scan and go technology is the retail industry’s ace card.

Imagine your customers walking into your store, swiftly selecting what they need, and heading out without long lines or time-consuming payment procedures. Scan and go technology integrates with mobile payment systems to enable contactless payments, such as mobile wallets or NFC payments, reducing the transmission of germs and bacteria during the payment process. That smoothness is not a distant dream: scan and go promises a quick, touch-free shopping spree while making things slicker for store owners.

With scan and go, retailers benefit from happier customers, easier access, greater efficiency, less waste, and heightened convenience. It’s not just about speeding through checkouts; this tech offers insights into shopping trends, allowing businesses to refine and elevate their product range.

However, the introduction of this technology brings forth challenges, from addressing potential security risks to ensuring a seamless experience for all, considering varied levels of tech adaptation among customers.

Join us as we delve into the dynamic world of scan and go, exploring its diverse advantages, challenges, and practical applications.

The evolution of scan and go technology

Tracing its roots in the retail scene, scan and go technology goes back to the pioneering days of the self-service supermarket model introduced by Piggly Wiggly in the early 1900s. This concept allowed customers to roam aisles and select items by themselves, promising lower prices in exchange for the extra effort.

The evolution continued with the introduction of self-checkout machines in 1986. Designed primarily to reduce labor expenses, the first of these systems, patented by CheckRobot in Florida, was rolled out in a few Kroger stores. In this early iteration, customers would scan their chosen products, send them down a conveyor belt to be bagged by a store employee, and then finalize their purchase at a designated payment area.

Despite the initial hype and expectations, widespread adoption took time. By 2013, the concept began to evolve further. Walmart introduced its "Scan & Go" in select stores, empowering customers to use handheld devices to scan items while shopping.

Another major event in the area of scan and go development was where Amazon unveiled a groundbreaking concept: "Amazon Go" in 2016. Distinguishing itself from previous models, these stores employed advanced sensors and computer vision, allowing customers to pick up items and leave, as the billing was handled seamlessly in the background.

Other early adopters were:

  1. Supermarket chain Kroger has introduced their own versions of scan and go technology "Scan, Bag, Go".
  2. Sam's Club, a part of the Walmart family, also introduced a "Scan & Go" system, allowing members to scan items as they shop and pay directly from their phones.
  3. In Europe, Sainsbury's in the UK tested a mobile-based scan and go system in select stores.
  4. Tesco followed in the footsteps shortly after testing and starting a trial of “Scan Pay Go” app in 2018.

As more stores adopt scan and go, it's important for both shoppers and businesses to understand how it works. We'll walk you through the basics, from the moment you spot a product to when you leave the store.

Scanning Items:

With the "Scan and Go" app, customers simply scan product barcodes using their smartphone's camera, and items are added to a virtual cart. If any barcode poses an issue, a minor adjustment or assistance from staff can easily resolve it.

Handling Special Items:

There are particular items, such as fresh produce or alcoholic beverages, that require additional steps. For instance, customers may need to weigh a vegetable or verify their age for certain purchases. It is important to offer clear guidance and provide support when needed.

Completing Your Purchase: Digital Receipt

Once all selections are added to the virtual cart, customers finalize their purchase directly within the app, simplifying the payment process. They can also opt out from a variety of payment methods and are promptly provided with a digital receipt. This modern method efficiently sidesteps the need for traditional checkout counters.

Self checkout vs scan and go vs grab and go

Intelligent stores offer different checkout methods, each focused on speed and convenience. To help clarify these methods, we've put together a comparative table that outlines their descriptions, similarities, and differences.
