Bar Owner Builds an Alarm That Stops You From Forgetting Your Credit Card | Hack Job | WIRED
Do you know what the most frustrating part about owning a bar is? When customers leave, but forget their credit card at the bar! What if we could stop that from ever happening? Mark Kleeb, bar owner and creative technologist based in Brooklyn, has been challenged to solve this dilemma in one week. Find out…

Hey all, thanks for watching! This was a fun project and I’d be glad to talk about any aspect of it

Is there a reason you tried GPS at all to begin with? This feels like a story device since I wouldn’t expect someone with your expertise would think a GPS solution indoors would be a good idea. Even if it did, you wouldn’t have enough location resolution to pin point if they are at the door vs if they are at the table 5-10 ft away. Lots of false positives, and probably also late positives when a customer leaves before the GPS location updates and transmits the new location to the system.

Thanks Mark, very clear explanation of concepts without getting too far into the weeds. I definitely appreciate you taking the time to show things that worked and didn’t as well as explaining why.
A possible elegant solution for the exchange token would be something that benefits the user in both scenarios. For example, give them a discount if they return the token (kinda like those quarter-fed shopping carts). It could be in the form of a durable business card that displays a message “looks like you left your card, return back tomorrow and get a discount off your next tab.”

wasn’t just having a huge sign on the door just sufficient to get people to close their tab? You know, without all the coding and tracking…

cool, i love stuff like this. Though the evaluation between GPS, bluetooth, and RFID was like evaluating a sedan, minivan, or pickup truck to haul a load of dirt. It’s kind of obvious if you know what they are, without even experimenting.

Wait, would you take the wrist band back once they get their credit or debit card back? Or will it sent the card to

Completely impractical idea and poor execution.
It’s a ‘cute’ idea however, we already have low-tech solutions for such problems and also with new technology and electronic payments/pre authorisation; this is never a problem anymore.

One thing i dont get, how are you going to get this on the customer, and what if they didnt forget the card? They’re going to set off the alarm anyways?

When you give him your card he trades you the bracelet and when you get your card back you either take it off your self or he cuts it off.

This is super cool, but they should just make taking apple pay mandatory
Mark Kleeb
June 4, 2021 at 2:29 pm
Actually by law you can’t limit the payment methods in a business. We have to accept all forms of payment. Though Apple Pay certainly makes things easier!

Sorry to be a bit dim here, but why do people leave their cards at the bar? I would imagine this voids the terms of the card, as you’re not supposed to give them to a third party. I’ve never seen this done here in Europe. Cheers.

Its the best way to make sure the tab actually gets paid and they don’t leave without paying.

@rifenbug meanwhile the credit card company won’t pay any damages, when you give your card away willingly to a bar tender you don’t know.. it’s such a stupid system..
Jonathan Irons
June 4, 2021 at 5:33 pm
@rifenbug Thanks. But I still don’t get why they don’t just pay for their drinks. I’ve genuinely never encountered this, even on US trips. Is it normal in NYC to open a tab?
Jonathan Irons
June 4, 2021 at 5:34 pm
I mean, I get this was a tech project, and I like that, but surely there’s a totally simple analogue solution to this perceived problem.

@Jonathan Irons This is the norm for basically every bar in NYC. You give the bartender your card and they hold onto it for the night, and every time you order a drink, you just tell them your name. You could technically just pay for your drinks one at a time, but that means every time you order a drink, you’ll hand over your card, they’ll swipe it, give you a receipt, and you’ll have to sign it and add tip. By creating a tab, you only have to do that once at the end of the night. It saves everyone’s time, which is especially important in crowded bars.

@MickTheAnt Thanks! I didn’t know that. Sounds like a lot of admin 😉 But I live and learn! Cheers.

Why would you give your credit card to the bartender? This makes zero sense to me. Seems like he is going just over the simplest solution. Not taking a credit card.

In the Netherlands we already have something like this. If you leave your card in the terminal it beeps like crazy.

I dont get it how closing your tab is connected to forgetting your credit card?

If you’re giving them ridiculous bracelets to wear, wouldn’t that be enough to serve as a reminder that they are forgetting something?
If they want to leave the card on purpose, they will remove the bracelet. And if you do a bracelet that can only be removed when they close the tab (lol, overkill i know) then you might risk not getting any more returning customers.

I would of replaced the alarm sound with TTS or sample audio voice telling them they need to close their tab.

Stop thinking of how to fix stupid and start things of how to remove it as a factor. Many bars of registers that can temporarily hold the card info after entering once. So no need to keep that cards.

June 15, 2021 at 3:57 pm
an even simpler solution, have “tab cards” made with the bars name and address on it that the customer can put in place of their card and will know exactly where it is if they forget
