Costco's 8-Second Self-Checkout Is Here, and Workers Say It's a "Disaster"
If you've set foot in a Costco on a Saturday afternoon, you know the drill. The cart traffic jam. The existential dread of picking the "wrong" line. That moment when you realize the person three carts ahead is paying with a personal check written in calligraphy.
Costco knows this too. And they thought they had a solution.
Enter the 8-second self-checkout — a new prescan system that's supposed to get you from cart to receipt faster than you can say "Kirkland Signature." CEO Ron Vachris told investors the company has begun deploying systems that allow employees to scan items in customers' carts before they even reach the cashier. Once you reach the register, you scan your membership card, all your items magically appear, and you just pay. Done. Eight seconds, give or take.
Sounds like a dream, right?
Well… the workers on the front lines have a different word for it. And it's not one you'd say in front of your grandmother.
"It's been such a f–king disaster," one employee shared on the CostcoEmployee sub-Reddit. "Our GM is now bragging about how much better our prescan numbers but now lines are even worse and both members and employees are pissed".
So what went wrong? And why does this "efficiency" upgrade have the very people it's supposed to help ready to pull their hair out?
Let's get into it.
What Exactly Is Costco's New 8-Second Checkout?
Before we dive into the chaos, let's clarify how this thing is supposed to work.
While you're waiting in line, yes, you're still waiting in a line, a Costco employee comes up to your cart with a handheld scanner and scans every item you're buying. This happens before you reach the register. Then, when it's your turn at the self-checkout kiosk, you scan your membership card and, poof, your entire cart's worth of items pop up on the screen. All you do is tap your card and go.
Costco CFO Gary Millerchip told investors the new technology allows for "an average transaction time of around eight seconds". That's compared to current wait times that some customers report can exceed 20 minutes.
On paper? Genius. In practice? Well…
The Promise vs. The Reality on the Ground
Costco says "early results show this is improving the flow of traffic, and we have received great member feedback".
But if you spend any time scrolling through employee forums, or just talking to the person in the red vest who looks like they've seen things, the story is a lot messier.
One employee put it bluntly: "It's a pain… It's slower now. You have one cashier pre-scanning everything, holding up the line, and members trying to skip the line, which makes the people waiting even more frustrated because others aren't following the rules".
So while the payment step might take eight seconds, the whole process is creating new bottlenecks that didn't exist before.
The "8-Second" Claim: Marketing Spin or Meaningful Change?
Here's the thing about that "eight seconds", and it's worth pausing on this because it's a classic case of corporate math.
The eight seconds is only the time it takes to pay once you're already at the kiosk. It doesn't include the time you spent standing in line waiting for someone to prescan your cart. It doesn't include the time the prescanner spent hunting for the barcode on that awkwardly-shaped rotisserie chicken container. And it sure doesn't include the time you'll spend waiting for the receipt-checker at the door.
As one frustrated customer pointed out on Reddit: "Eight seconds is bs. That's the time to pay only. But to get there, you are still in a line. Still waiting for a scanner person to show up. Waiting for those ahead of you. Waiting in that awful line to check receipts".
So yeah, the stopwatch starts after most of the work is already done. Handy, that.
Why Costco Workers Are Calling It a "Disaster"
Alright, let's get to the heart of it. Why are employees, the same people who usually sing Costco's praises for decent pay and benefits, so fed up with this new system?
"It's a Pain… It's Slower Now", The Bottleneck Nobody Predicted
The prescan model sounds efficient until you realize you're essentially creating a mini-checkout inside the line itself. One employee is now responsible for scanning everyone's carts while they're still waiting, which means:
- That employee can only scan one cart at a time
- If someone has a massive haul (it's Costco, after all), the whole line stalls
- People get antsy and try to cut ahead
One Reddit user in a Costco employee thread summed it up: "Pre-scan for registers works nicely because no one is itching to cut in front of you while you scan. Pre-scan for self checkout is an absolute ticking time bomb before members argue about cutting while you scan".
Cutting in Line and Customer Confrontations
Nothing brings out the inner beast in otherwise pleasant humans like a perceived line-cutting incident. And this new system is basically inviting that conflict.
When there's one prescanner working their way down the queue, some customers try to "help" by jumping ahead, which infuriates everyone behind them. Employees are now stuck playing referee, managing the emotional state of an entire line of hungry, over-caffeinated shoppers who just want to get home with their 48-pack of toilet paper.
Missed Items, Double Charges, and System Glitches
Then there are the technical hiccups. Because what's a new technology rollout without a few dozen things going wrong?
One employee vented: "I hate it. It usually ends up taking longer than just taking the stuff out of the basket and ringing it up at the register. At the register, I've had so many mistakes from the people prescanning. Missed items, double charges. Why does Costco hate technology that actually works?"
Another shopper described a firsthand experience where they got double-charged for a case of soda and had to wait for an associate to manually fix the error. So much for "eight seconds."
Is Self-Checkout Failing Everywhere?
Costco isn't alone in this struggle. Across the retail landscape, the self-checkout experiment is showing serious cracks.
Research indicates that self-checkout eliminates cashier jobs and replaces them with a smaller number of high-stress monitoring and assistance roles. Some studies even suggest that introducing self-checkout has increased the workload for cashiers.
And it's not just about employee stress, theft is soaring, and many retailers are quietly scaling back their self-checkout footprint or reopening staffed lanes. After years of automation hype, we're seeing a partial return to human cashiers, not out of nostalgia, but out of necessity.
Costco's approach is different because it's a hybrid model (employee prescan + self-pay), but it's running into the same core issue: automation works best when it genuinely simplifies the process for everyone involved, workers and customers. When it just shifts the burden around without addressing the root problems, you get… well, what we're seeing right now.
What Can Costco Do to Fix This?
Look, I'm not here to dunk on Costco. I love Costco. The $1.50 hot dog alone deserves a Nobel Prize. But this rollout clearly needs some TLC.
Here are a few suggestions, from a very non-expert observer who's just listened to a lot of exhausted employees vent:
- Add more prescanners per line. One person scanning dozens of carts is a recipe for bottlenecking.
- Create a separate "express prescan" lane for customers with fewer items.
- Improve training for both employees and members. Several workers noted that "we just don't have the hang of it yet and nor do the members".
- Fix the double-charging and missed-item glitches. Technology should reduce errors, not multiply them.
- Consider letting customers scan their own items with the handheld guns. As one commenter noted, "It'll work if they let customers use the scan guns, but they just refuse".
Sam's Club already offers a "Scan & Go" app that lets customers scan items as they shop and pay digitally. Some Costco members have admitted they switched to Sam's primarily because of that mobile scanning system. That's a wake-up call.
Efficiency Shouldn't Come at the Cost of Sanity
Costco's heart is in the right place. Long checkout lines are a real problem, and trying to solve them is admirable. But this 8-second prescan system, at least in its current form, is creating more friction than it's removing.
Workers are stressed. Customers are confused. And the "eight seconds" of payment time doesn't mean much when you've just spent 15 minutes in a line that's moving slower than ever because one employee is trying to scan everyone's cart while dodging line-cutters.
If Costco can refine the process, fix the glitches, and, most importantly, listen to the people on the front lines, this could become a genuinely helpful innovation. Until then, it's just another thing for employees to vent about on Reddit.
And honestly? They deserve a whole lot better than that.
