Comprehensive Guide to Self Checkout Systems in 2024Comprehensive Guide to Self Checkout Systems in 2024

According to surveys, 60% 1 of people are irritated with long checkout lines. Self-checkout units are installed to prevent the long queues at the market and improve the shopping experience. Today, self-checkout systems continue to attract tech giants like Amazon and Walmart.

This article explains self-checkout systems with all different approaches to self-checkout and highlights the advantages and challenges of these systems.

What are self-checkout systems?

Self-checkouts (SCOs) are machines customers use to complete their purchases. The machines remove the traditional staffed checkout. Self-checkouts are also known as assisted checkouts (ACOs) or self-service checkouts.

With Self-checkouts, customers grab the products, and scan them through barcodes. They complete their shopping without any assistance. Self-checkouts are commonly used in supermarkets. One or two staff members supervise Self-checkout areas to assist customers in case of problems.

What are the different approaches to self-checkout?

There are different self-checkouts with various approaches. All these approaches have their unique pros and cons:

Self-checkout units

Some convenience stores have already been using self-checkout machines in their stores for a few years. They have some advantages:

  • Shorter lines and faster checkout
  • Improved privacy
  • Greater accuracy
  • Reduced labor cost
  • Better in-store optimization thanks to the availability of new space with a reduction of queues
  • Improved Customer experience

Despite the advantages, the implementation costs are high. A typical four-lane setup costs $125,000 to install. 2

Self-checkout units with RFID

DXC Technology along with Harting Systems and Murata launched a new RFID-based self-checkout counter in 2020 (Yes, it appeared that I was not alone).3

Retailers can label all their products with RFID tags. When customers place their shopping bags on the counter, all the products get scanned at once without any effort and the counter displays a full list of the products and total price.

This technology reduces the time spent on the entire checkout experience to 30 seconds.

For this technology to work, all items need to be tagged with RFID tags and these potentially expensive checkout machines need to be installed in stores.

A company called Automated Stores produces customized vending machines to provide automated checkout experience. 4

Vending machines automate the checkout experience and is potentially more secure than other approaches. However, vending machines put a glass between products and customers and do not allow them to touch products before buying. In addition, these machines are also expensive hardware.

Barcode scanning solutions

Snabble is an app that enables customers to scan their purchases in retail stores, pay online and then walk out. 5 The app is in use in markets called Knauber in Germany and Frankfurt <IKEA. Though the Snabble app is good overall, there are some problems while reading barcodes, such as

  • The low print quality of a barcode is too low
  • Low quality of your mobile phone camera
  • Specific barcodes are not priced in the system.
  • The system also provides limited security for retailers as end users are in charge of the whole process.

Self-checkout vs. Checkout Free systems

Checkout-free stores are a different approach to self-service checkout. In this approach, customers do not line up to scan their items. The products they grab are identified, and the bill is directed to their phone automatically. You can grasp more about checkout-free systems in the comprehensive guide article.

There are 2 types of vendors in checkout-free systems. The first one develop and install the technology to use it in their company stores, such as Amazon Go, Walmart, and Standard Cognition. The other type of vendor develops systems to provide white-label solutions for third-party stores. Grabandgo and Trigo Vision are known examples.

What are the disadvantages?

Even though it sounds amazing and provides a peerless customer experience while reducing labor costs, it has some disadvantages.

  • Security
    • All purchases and transactions are made online with pre-registered credit card information. Some users will be reluctant to get their credit cards stored
    • Inventory Loss No matter how advanced the technology is, there will be people trying to steal because employees are unable to monitor customer transactions as closely as self-checkouts. While some technologies try to minimize theft, some technologies such as barcode scanning solutions rely on users’ compliance.
  • Lack of Personal Interaction
    • Although the key benefit is eliminating customer engagement to decrease waiting times, customers may prefer to have a one-on-one interaction with cashiers.
  • Implementation difficulties
    • Sometimes bar codes and coupons don’t scan properly, some products such as alcoholic beverages require age verification, or customers need assistance.
