My main beef with these menus is that I can't see the entire menu on my phone screen, and end up scrolling up and down multiple times before I can decide what I want to order. With a paper menu my eyes can flick up and down much faster. It's like trying to edit spreadsheets on a phone - technically possible but a real pain in the arse.

At least the screen is only touced by you. My peril are the touch screen ordering places (practically all fast food places nowadays) where based on their outlook hygienically challanged persons swipe their fingers up and down for long before you have a chance following them. There is an icecream place opened nearby I had no chance trying because they only have touchscreen order. Guys at the till only serve icecream a…

I don't mean to be too forceful about this, but how is a common touchscreen ordering system any better or worse than the door handle you used to walk in?

Yes, agree. at the same time, the company bears significant responsibility under the law. Their unconventional and insecure API implementation likely violates multiple provisions of the Act. They could face substantial penalties and legal consequences for failing to adequately protect personal data and implement appropriate security measures.

It's not hard . It's just a bit more work - enough that it starts requiring a professional to be involved (graphics design, photography, coordinating print), whereas traditional menus can be half-assed[0] by anyone with passing familiarity with Word and access to the office printer. In contrast, the digital menus usually come as a solution, packaged with a promise of some juicy business analytics, so the restaurant o…

I would expect the most expensive part to be printing and laminating those menus, which will also be longer due to the space used on images. Then they need to be cleaned, possibly updated, and will still go bad over time.

Printing is cheap and, even with a half-decent consumer-grade inkjet or laser printer, takes very little labor. Laminating is much more labor-intensive, though it's not bad as long as you stick to a standard paper size[0].

In my experience, somehow, in the transition to digital and past worries about "dead trees", most people missed the fact that paper and printing are dirt-cheap these days[1], and if you account for e-waste, often much more environment-friendly than digital alternatives.

[0] - We bought a laminating machine recently, so my wife could make various educational tools for our kids herself. It quickly stops being fun once you're trying to laminate a bunch of arbitrarily-cut shapes on a single shit; keeping things aligned is a PITA.

[1] - Well, not if you're paying a print shop. I think that biases the intuition for many. Even color printing is too cheap to meter if you have a half-decent printer at home.

I don't understand the privacy part. If you order through a waiter, they still record what you ordered.

They may record what I order (although the cafes and restaurants I go to use pen and paper or just plain-old human memory) but that's it. Even if they enter my order into some system for analytics or what have you, there's no cookies, no tracking, no transparent pixels, etc. Look, all these micro-arguments about the micro-invasions of privacy are 'bread and circuses' [0]. We've entirely lost sight of what it means to…

There is already tracking via your credit card if you're paying that way, which most people do. I don't want to lose sight of that.

> The coup de grace is I don't even get a discount for the degraded service. It's like self-service checkouts: the store gets to save on stuff and get their customers do the store's work instead, and we don't even get a discount for that free labor and more time spent in checkout and degraded experience.

I will gladly do the work myself if it means not being stuck behind people chatting up the cashier or doing complicated coupon/return/exchange/gift card transactions. The value is in the consistency and predictability of time spent for someone who just wants a single bag of onions or a single T-shirt. If stores had no-BS lanes (more than just "X items or less" lanes) operated by human cashiers I would use that too, b…

> The value is in the consistency and predictability

"Consistency" and "predictability" are not the words I associate with self-service checkout. Maybe I'm spectacularly unlucky, but almost every time I use one of these machines with more than 3 products, the machine will get confused about the weight, or decide to randomly check me, or find another reason to lock up and have me wait for a clerk to show up and unlock it, which takes anything between 1 to 5 minutes. And I'm not the only unlucky person, either - I see it happening often enough to others, which usually reassures me that I made a good call standing in the queue for the old-fashion human-operated register.

I like to scan the "specialized" bar/QR codes I come across in my daily life in case they're not just URLs. Sometimes I find some interesting stuff and possibly some opportunities for mild exploits. The other day I was at burger king. They allow you to refill your drink as many times as you like within 60 minutes of purchasing it, and the way this restriction is implemented is by having you scan a QR code they print…

>Can you craft a QR code with the same data but change the timestamp to achieve for infinite refills?

I'm hoping nobody is this naive to let your client have mission critical info to implement something as crucial as giving a discount or refills in your case. It would be just be an extra column in your db table, the only identifier available to the user should be just the UUID, along with some identifier.
