Opinion: For Aldi, Checkout-Free Makes More Sense Than Self-Checkout

A busy checkout day at our local Aldi.

EDITOR’S NOTE: Like all posts on Aldi Reviewer, this piece is the opinion of the respective authors.

While much attention has been paid to online shopping in recent years, either delivered to your home or picked up curbside, most customers still do their shopping in-store. There are a lot of reasons for that, including the fact that online shopping often has added costs and because shopping online has its own set of hassles. Some customers, too, just like to be able to see their food before they buy it.

With in-person shopping alive and well, companies are trying to innovate in those experiences, too.

Competing In-Store Technologies

In the fight for the future of in-store grocery shopping, there are currently two technologies front and center. One of those is self-checkout, which is now common in many grocery and big box stores. With self-checkout, customers scan the products themselves, bag the groceries themselves, and then pay at the kiosk and leave. Self-checkout is about as divisive as politics: some customers love it, and others hate it.

The other is checkout-free. With checkout-free, a customer checks into a store with a smartphone app, then goes around the store, picks up whatever they need, and then walks out when they’re done. A combination of technologies, including the app and store cameras, track what customers pick up and set down, and those technologies then determine what the customer bought and then charge the customer’s credit card through the app after the customer leaves. This technology currently exists in the form of Amazon Go, a pet project of Amazon in a handful of cities across the United States and United Kingdom.

Aldi and the Future

Aldi is right now piloting both technologies. On the self-checkout front, Aldi is testing the concept in several countries, starting with the United Kingdom a couple of years ago and expanding more recently to Australia and the United States. Interestingly, Aldi US has been silent about its pilot, which launched in Ohio without any announcement whatsoever, not even a press release. I wonder if divided opinions over self-checkout are part of the reason for the silence.

More recently, Aldi has dipped into checkout-free technology. In September of 2021, Aldi UK announced in a press release that it was piloting a checkout-free store in London. This store would operate much like Amazon Go, where customers would check in with an app, pick up what they need, and then be automatically charged when they leave.

At the time of this post, we’re a long way away from having checkout-free Aldi stores everywhere. Checkout-free technology is much more complicated than self-checkout, requiring several technologies to work together accurately and effectively. Aldi UK — which seems to be on the forefront of many Aldi pilots, including in-store grocery pickup and shipping of limited buys — has been testing the technology with Aldi employees but nothing has opened to the public yet. Amazon Go took more than a year to go from testing to public opening, so it’s probably going to be a while before Londoners have a store to try. For Aldi shoppers in other countries like the United States and Australia, it will be much longer. Years, probably, and even then only in select places to start.

What Makes More Sense for Aldi

All things being equal, we think Aldi and checkout-free is a better marriage than Aldi and self-checkout.

Among the things that make Aldi different, two of the biggest are speed and efficiency. Aldi aims to make its checkout experience as fast as possible, and it aims to make its stores efficient enough to keep prices low. That’s why many Aldi products have multiple bar codes to make it easier to scan products, and why customers use a quarter system to return carts rather than have employees do it.

Self-checkout certainly keeps costs low by reducing the number of checkout employees, but it doesn’t necessarily win points in the speed category. It’s hard to see an average customer scanning groceries faster than a trained Aldi employee. I’ve been in plenty of self-checkout lines, and even customers with just a few items can take a while. Self-checkout might have value as a supplement to Aldi employees, but it’s also not hard to see how self-checkout lanes could get bogged down, especially if there are hiccups. And anyone who has used self-checkout and heard the kiosk say things like “please place the item back on the counter” or “please wait for an attendant” knows there are often hiccups.

Checkout-free, though, wins on both counts. It wins on speed, because there is no checkout lane; in fact, customers can even bag their groceries in the store aisles before they leave. And it wins on efficiency, because you don’t need to pull workers off their other duties, like stocking aisles, to man the checkout lane.

Potential Pitfalls of Checkout-Free

Some people might object to checkout-free as taking jobs away from workers. That’s a legitimate issue, but also not one Aldi is probably going to lose a lot of sleep over. Aldi has always been a lean operation, focused on keeping staff down so prices also stay down. The quarter you put in the cart, and the fact that you bag your own groceries, take jobs away from workers, too. (To be fair, Aldi also generally pays its workers well.)

Another issue is access. To use checkout-free stores, you would need a smartphone that could use the app and make the purchase. In the United States, there are bound to be people, especially those in poverty or elderly shoppers, who don’t have the technology to make it happen. Given that Aldi is a popular option for many low-income Americans, it’s hard to see Aldi US replacing cashiers in all of its stores, at least not in the near future.

Closing Thoughts

Right now, the issue is probably academic: Aldi isn’t close to a checkout-free experience, not right now, while it’s a lot closer to implementing a self-checkout experience. For that reason, you’re probably likely to see a self-checkout lane in your Aldi long before you can just walk in and out without a lane at all.

But I think that, in the long term, checkout-free will do a better job of helping Aldi do what it does best — namely, making for a fast, low-cost experience. It’s just a matter of getting there.

  1. I think it’s also fair to assume the >10 years old self-checkout tech would have a easier time to receive improvement than the checkout-free technology. It may also require less ongoing maintenance for widespread implementation.

    A pitfall not mentioned for the checkout-free is, often the manager’s discount and yellow tag price are not reflected in the checkout system. Everytime i get any yellow tag items, I simply take a picture of it. And 9 out of 10 times, I ‘ll need to talk to a manager about my receipt. I can’t imagine how a checkout free system would correct that without risking being exploited by both parties.

    I do think both would improve my experience as a customer.

  2. The Scan and Go technology that Sam’s Club implemented is the best of both worlds. You scan items with the phone app as you place them in your cart. When you’re done shopping, you pay with a single swipe in the app using the credit or debit card you have on file. The app generates a barcode that you show when exiting the store, an employee scans it along with a few items in your cart and you’re on your way. I love using it, I don’t know why Costco and Aldi haven’t done something similar.

  3. Catherine A. McClarey

    I hate doing self-checkout in most stores, largely because I prefer to write paper checks to pay for my purchases, and those always require an attendant if used at a self-checkout. Since Aldi doesn’t take checks, self-checkout + cash payments aren’t too bad as an alternative, and would certainly speed up checkout, just by reducing the lines which form when only 1 or 2 traditional checkout lanes are open. I discovered while on vacation this summer that Aldi now accepts credit cards at checkout, too (at least in Indy), which was a great convenience. My problem with a checkout-free system is that I don’t always have my smartphone turned on, or I might leave it plugged in at home to recharge during the day. I also don’t usually like to pay for groceries via credit card (the vacation shopping trip being an exception), because I don’t like to run up my credit card bill, and it’s far easier to stick to a budget if the available funds for groceries are something very concrete like cash in my wallet.

  4. This doesn’t alleviate the problem of our Aldi’s never putting enough cashiers on. Can be up to 10 carts waiting in line and no one “sees” until a customer calls for another cashier.

    • Roxy, I agree with you. Too many times, I have been in a line that is as long as the isle. I’d like to see an express line for customers with less than 15 items.
      I always allow customers with just a few items to go in front of me but not all customers do this.

    • I think this is common of most Aldi’s. Once the 2nd cashier is summoned, the line is immediately halved from 10 to 5. In all the years I’ve been going to Aldi, I don’t think I’ve ever been in line for more than 7 minutes. Seems like the peak average is usually 5 minutes.

      • Ditto what Alex said. When the line starts getting long, I’ve never had to wait more than a couple of minutes before they open another register. I always get through the Aldi checkout lines quickly. Can’t say the same for other retailers.

  5. I don’t trust my cell phone in general for thing like this. I do use it for my shopping list, however.Another grocery store I sometimes go to has free type checkut, and I have no idea how to figure out how to do it. My cell phone is 8 years old. I like it and have a new third party battery so hope to use it a lot longer. Some new apps won’t even acknowledge my phone and I right now do not want a newer one. I actually prefer to stand in line. So far the Aldi stores I go to do not ave automatic check out. Fine with me. Takes more work to check the items, bag them, etc. Okay if I only have a few items. I feel like I am doing a service and not getting paid for it when I do go to other stores that have auto check outs.

  6. I love Aldi checkout. It is quick and efficient and after payong, you then get to take your cart to the bagging area where there is enough space and time to bag efficiently at your leisure. Self checkout, I hate. The machines are buggy and there isn’t enough space.

  7. Aldi check out is fast as is. Plus I get to bag the way I like.
    Self check out has pros (self bagging) & cons -usually associated with waiting for employee help (miss-scans, ID for alcohol sales, coupons).
    Hand-held shop-n-scan devices are a convenient but pose their own 7th circle of hell.

  8. Aldi is the only store where I look forward to the self checkout. The speed at which the system recognizes the product is phenomenal.
    In addition many of their groceries have the UPC code on more than one location and this reduces searching.
    The only time I’m puzzled sometimes is when fruits and veggies are to be scanned, yet I’m getting better identifying them.
