Many commenters haven't read the blog post. A retailer app or Amazon One account is not necessarily required. From my understanding, you can simply enter with a credit or debit card.

> Consumers can enter a Just Walk Out technology-equipped store using one of three methods—method types available can vary by store: (1) Amazon One, a contactless identity service that uses your palm to pay; (2) credit or debit card; or (3) app-based entry, using retailer-branded apps.

Meh - I was excited by JWO but it now looks like self-checkout will win because it works pretty well these days, and it handles all the corner cases including product sold by weight, large items, identical-looking items (common in grocery), etc. With self-checkout, you don't need an account which is crucial for travelers. Self-checkout also supports cash for the unbanked. I've tried SC in multiple countries, just hit…

They could add back in the job where someone else presses the button in the elevator for you, that would also create jobs.

No need to be whimsical about it. But, yes, that's par for the course coming from an IT-focused forum, to hell with people in need of low-paying jobs, and we also don't want to speak with them, our lives are way too important for that.

Ideally, as more jobs are automated and less work is needed, a robust welfare state would provide people with income so they wouldn’t need to do jobs that exist purely to employ someone.

Many people who work such jobs are mothers who wish they could spend more time with their children, adults who wish they could care for an aging parent, students who should have more time studying and socializing, etc.

I just returned from a trip in Asia where 50% of machines did not accept any of my cards. In one case (parking garage) I asked a passerby to pay for me with their card, and gave them cash. While I enjoy that I can pay everything by card at home, and mostly stopped going to the handful of places that don't accept cards, I do appreciate the fact that cash is usually available as a backup.

Many American credit cards don't support some of the security features required in other countries. For example they might not support the card itself knowing your available balance so that small transactions like parking can be done entirely offline, and the parking garage collecting a cryptographic proof from your card that you have $3.50 available in your account. Remember that to do this, your card has to offer s…

How can this work if you have online or recurring charges? It seems like a lot of work to still not know the balance.

Expect to have to install an app for every store you want to go into over the next few years with all the accompanying snooping. This tech is a wet dream for retailers. Who needs store cards when they can just see in realtime what you're picking up and putting back, along with your demographic data.

I used to resist getting a store card for this very reason, until I realize that they can track me through the credit card that I used anyway. This requires the self checkout machine to record the credit card number from the POS though - does the POS expose this information?

“Creates extra jobs” has a pretty direct linkage to “drives higher prices”. If the job is extra/not needed, some consumers will rationally prefer to self-serve (for whatever connotation if that you prefer).

Then those "not needed" will rationally (and in many instance literally) kick those rational consumers in the head, in order to have something to put on the table. It's as simple as that. And then it becomes a race of "let's better fund the police so that we'll keep the not needed at bay" vs "maybe it's just not good policy to kick the not needed while they're down, maybe it's not all their fault".

We should be expecting a smaller proportion of the population to be working in most sub-sectors of the economy each year, as new, innovative areas provide opportunities for relatively inexperienced people with high aptitude to work more productively and earn higher wages. It's fine having people bagging groceries at supermarket checkouts, but that isn't really going to work out in the coming years if those same people are going to be demanding state-of-the-art medical treatments, developed-world retirement benefits and cutting-edge consumer goods.

The POS can store anything that can trace a customer. It wouldn't be hard to derive a unique token from the credit card information, so it doesn't have to deal storing anything sensible.

This tech can be a wet dream for retailers but not if Amazon is providing it.

Retailers hate Amazon up to the point to avoid AWS - there are exceptions - to any of their cloud infrastructure.

It isn't a perfect system. The bank guarantees they will pay for any charges that the card digitally signed, and the bank will take any losses.

Most banks typically authorize the card to make ~$150 of payments or so offline. Anything bigger, or for risky customers or those with a low balance, it needs to be an online transaction.

The benefit of offline transactions is they can be done in under half a second, compared to the 5-10 seconds online transactions take. For things like opening the barrier in a car park, 10 seconds is too long.

> it works pretty well these days

Maybe in select stores?

I personally experience more headache than great UX using self checkout in most stores.
