I tried out Amazon Go in SF and I have to say that I'm very impressed. It doesn't even require a standalone app if you already have the Amazon app downloaded. I walked in, scanned my phone, grabbed a sandwich and walked out. It took 2 minutes and felt a lot less friction-y then buying something at a convenience store, which admittedly was low friction to begin with.

Yesterday I had a similar experience with a cafe in a smallish town (Malvern, PA). However, instead of using an app system, they relied on the "honor system". I would be curious as to their annual losses, and how that would vary when in a metropolitan area such as SF.

That's cool, but that would be a hassle for groceries if you had to manually add up all your purchases. The app allows you to combine security with customer convenience.

We have a trust-based beverage PoS at our hackerspace. The bottle crates are just standing there and everyone is trusted to pay into the cash desk next to the crates when they take bottles out. Our weekly losses (i.e. bottles and money not accounted for) average ~40€, with weekly revenue around 200-300€. The losses are factored into the prices. Prices are comparable to or slightly below convenience store levels.

Is there a mechanism for IoUs / credit lines for members?

I've seen trust-based mate shops at hackerspaces around the world, and I've been told that the ones that have a credit system (even one that's not limited, checked, and that's not even authenticated) end up actually not having any significant losses. Like, anything from a piece of paper with people noting down unpaid mate purchases to things like android tablets with a webapp letting you note that you put in a bill of N euros and taken out a bottle of mate.

Friction from being able to pay right away seems to lead to "I'll pay extra later" thinking, which makes people either forget or miscalculate how much they actually owe.

Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by majewsky on Monday July 08, 2019 @07:58AM (#20381946)
Yes, each member account has a balance without any restrictions in either direction, and it mostly works fine. At times, the negative balances pile up, in which case I write a mail to the mailing list asking people to pay their dues. Usually, the negative balances approximately cancel out the positive balances, both at something like 1000 euros.

Also, when your balance is negative, after every purchase there is a big red notification reminding you of that.

> and how that would vary when in a metropolitan area such as SF.

I've spoken with grocery store clerks in SF (at major chains like Walgreens) who were concerned that their stores might be closed because of truly excessive losses due to constant shoplifting. Of course the shrinkage is factored into the price, but you can only raise prices so much before it starts eating into your sales.

BTW, when I visited the Amazon Go in SF it actually seemed to have more staff present than a regular grocery store of comparable size.

Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by dontbenebby on Sunday July 07, 2019 @10:17PM (#20379434)
Especially if they save enough in personnel costs to cover the shrink. Maybe throw in some CCTV to catch egregious offenders.
Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by chongli on Sunday July 07, 2019 @10:34PM (#20379496)
CCTV seems like a bad move. It creates an adversarial relationship to the customers. For a small business, it would be better to cultivate goodwill and rely on community norms to police offenders.

People aren't likely to repeatedly steal from an honours system cafe if there are regular customers witnessing them.

Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by tylerhou on Sunday July 07, 2019 @11:20PM (#20379639)
But how do you distinguish between someone stealing versus someone leaving and paying through the app in their car?
Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by chongli on Monday July 08, 2019 @12:33PM (#20384110)
That no longer falls under the purview of the small, independent cafe on the honours system.

I'd say, in a cafe, besides cash you could have a touchscreen to key in your order and tap your phone to pay. The walk in walk out Amazon model is not an honours system, it's a technological policing model.

Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by thaumasiotes on Sunday July 07, 2019 @06:17PM (#20378330)
The obvious question now is what it tracks. Presumably if you pick up a sandwich and then put it down somewhere else in the store you shouldn't be charged for it. What happens if you walk in, pick up a sandwich, eat the sandwich, and leave?
Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by yazaddaruvala on Sunday July 07, 2019 @08:56PM (#20379088)
Moving stuff is seamless. You are not charged.

Passing items between friends that used the same phone to get in is also seamless (I’ve never tried passing an item between two amazon accounts).

I believe there are weight sensors to counteract stuff like taking out half a sandwich and putting the rest back, but I’m not sure about this one.

There are definitely ways to cheat the system. But the tech is at a point where it is similar hassle/consequences to other petty shoplifting that happens across the world (the cameras can always be checked by a human in a post-mortem).

The reality is convenience store shopping is at a point where it is almost always better for the company and the customer with Amazon Go tech.

The bigger problems with the Amazon Go tech is, how do you scale it to a supermarket size, how do you get around or change regulations that a human needs to validate ID for alcohol, how do you auto-stock the place, how do you get away from needing a human for security guard / first aid reasons? Also I imagine it costs a lot to set up. How do you make this cheap enough to be financially worth the ROI?

Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by btgeekboy on Monday July 08, 2019 @03:34AM (#20380672)
I think having the shop staffed isn’t necessarily a problem or failure. The original Go store in Seattle has alcohol (ID is checked by a person that permits entry into that section) and the store is otherwise staffed for restocking and general customer service. But I walk in, grab what I want for lunch, and walk out. I don’t wait in line behind 5 other people while waiting for the awkward chip card delay or that guy that wants to pay with pocket change that hogs the register. Consequently, I go there far more often than the 7-11 down the street.
Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by alexgmcm on Monday July 08, 2019 @03:30AM (#20380645)
You can still have a security guard or two - that just means you need two guards instead of two guards and half a dozen cashiers.

I agree with you - the stores will save more money by switching to this tech and it will be better for the customers.

I really hate having to queue for 10 minutes in a busy supermarket to buy groceries - it's probably the worst UX I experience on a regular basis.

Some people are just terrible.

I was in a supermarket sometime last year and saw a woman put a package of meat in the toilet paper aisle and walk away. She saw me staring at her and began shouting at me.

The world is full of awful people.

I worked in a supermarket for several years and this happened all the time. I could never figure it out, but basically some people would change their mind and dump things right where they were standing. Normally this isn’t a big big deal - we would just put it back in the correct spot but sometimes we’d get fruit and veges dumped in the freezer which would ruin them. That was particularly weird.

Does the app show you what you're buying and what it costs before you exit?
Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by tschwimmer on Sunday July 07, 2019 @05:35PM (#20378034)
No, it does not. There was a lot of latency (~2 hours) before I saw what I was charged for.
Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by perl4ever on Sunday July 07, 2019 @07:39PM (#20378753)
In that case I would be unwilling to use it. A normal checkout provides a point in time and space when what you are buying is reviewed and you become aware of the total and any errors. If someone says there will be no errors, I just roll my eyes.

I have no idea how many other people are like this, but I already don't look at my receipts when I'm in a grocery store. If I do, it's because I realized I forgot something and want to know if I actually forgot something. So for me, the experience ends up being the same.
Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by perl4ever on Sunday July 07, 2019 @11:13PM (#20379613)
Sure, I often don't pay attention either. But once in a while, I notice something wrong anyway, and also I'm free-riding on the fact that some people pay more attention.

A store that is arranging things so that there are no checks is a store that is going to profit from its own mistakes. Impersonal forces will drive it to do so regardless of particular human intentions.

People have been buying things and only getting an invoice at a later time for millennia, and managed fine.
Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by perl4ever on Sunday July 07, 2019 @11:30PM (#20379673)
Interesting you should mention invoices. I got my car repaired recently, and the invoice was about $1,000 more than expected. They assured me there would be no problem with the insurance, but obviously if they and the insurance company had their shit together, then it would have been reviewed and approved before doing the work. The insurance company may have eventually approved it and I hope to be getting a check soon, but the fact is, I paid them up front and have been left hanging for two weeks now. Neither business answers emails, calls me back, or does anything in a reasonable amount of time (it's been months since the claim). One told me that the delays of the other are in fact violating state regulations. Yet both companies are well-known and often recommended - I didn't choose them at random.

This is the sort of relationship I do not want to get into for ordinary purchases. It demands too much trust, which is hard to build and unnecessary for most things.

You get a receipt after you exit. And from the receipt there's an option to notify of a mistake. I've never had to use it yet, and I haven't had a mistake happen yet so I can't comment on how smooth that would be.

Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by perl4ever on Sunday July 07, 2019 @11:40PM (#20379719)
Perhaps, perhaps.

The issue I have is that once you add the friction in, it prevents errors from being corrected, and that reduces the incentive to prevent them. It's not about whether I can get a problem fixed when I notice it. It's that the number of problems will be higher because on average fewer will be noticed and fixed. Furthermore, whenever the rate of problems seems a little too high, the easy "fix" is to add a little more friction.

visibly priced, as in marked on the item, the location, or both.

Of course they are "priced" in the sense of the vendor assigning a price to deduct, but transparency to the purchaser is legally required.

Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by austhrow743 on Sunday July 07, 2019 @10:47PM (#20379542)
Item scanning can take a while, as well as queuing for it. Tapping card vs chip and pin is a tiny time saving compared to the whole checking out process.
Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by throwaway9d0291 on Monday July 08, 2019 @03:36AM (#20380683)
I live in Switzerland and for a small number of items I can usually be in and out of my regular snack supermarket (a regular supermarket, I just use it for snacks) within 120 seconds.

It's just walk in, pick up a drink and a snack, walk to the self check kiosk and scan both barcodes, tap a few times rapidly (you can just hammer a button in the same place a few times) and wave my card. If I had to guess I'd say the entire checkout process takes ~10s, most of which is getting my card out of my wallet.

This differs from a US self checkout in a few ways:

- I nearly always had to queue in the US. I nearly never have to queue in Switzerland, at least at this store. This may be because:

- Swiss self checkout kiosks don't weigh the bagging area like US ones do. In the US there's always a small delay between scanning items while you bag the item and wait for the checkout to detect it. In Switzerland you just scan it and the kiosk doesn't care what you do with it afterwards.

- Payment is extremely fast, like sub-second end-to-end fast. You literally just wave your card at the terminal.

- There are usually 15-20 self checkout terminals in the larger supermarkets you find in the city so unless you're there at a really busy time, they usually have more than enough throughput to deal with traffic. In the US I'm used to seeing <10 self checkout terminals.

Ugh. I will _always_ prefer friction to my own convenience if it means some person can have a job. I could care less about efficiency and I could care less about some shareholder's bottom line.

No you won't. Our standard of living is built on automation in a million ways, big and small.

Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for... by didibus on Monday July 08, 2019 @12:01AM (#20379799)
There's still one person to help at the door, one person to check ID for the alchohol section, a security guard, and clerks that fill up the aisles, refill the shelves, put things back in their place, etc.

Also, they have a kitchen attached to them, and prepare food in it, so they have kitchen staff for that and all the delivery surrounding it.

They also now need to hire engineers to work on the system, maintain and repair it, and service workers to setup and maintain the infrastructure needed in the store.

Honestly, I'm pretty sure the whole things turns out way more expansive for them than hiring a few cashiers. I think the idea is that the extra convenience given to the customers mean that customers will prefer to shop at Amazon Go instead of elsewhere, and that might be worth the extra cost to grow the marketshare.

You're mistaking the argument being made, which is really about recognizing ones own moral inconsistencies instead of claiming moral high ground over others where there is none to be had.

A tech worker who claims to value a cashier's job over their own convenience is basically gorging on two large deluxe pizzas while criticizing others for eating an olive.

Just look around you. Pick just about anything. A wall. A refrigerator. Your shoes. A spice jar. They all have stories to tell about automation and job loss.

It's a bit ridiculous making such a non-differentiating statement claiming to be against automation when that is a lot of what the digital revolution is about in the first place. No less on hacker news, which is one of the hubs to talk about the digital revolution.
