Another Beer Please

jmichaelg writes "What do you get when you combine a glass, a PIC computer, two capacitors, a coil and a zener Diode? A wireless beer glass that signals your waiter when you need a refill. The circuit is an RFID transponder that measures the fluid level in a glass and transmits a globally unique ID coupled to the fluid level reading when queried by an antenna hidden in your table. The query provides enough power to drive the circuit so no batteries are needed. A technical paper describes the circuitry in the table and the glass." This hit the news over a year ago, but we didn't have the technical details.

      WOW! I'm amazed at this technology, waiters simply looking at the glass and checking on their tables regularly would never work. I hope they come out with plates that somehow tell you when you're done chewing your food so people know when to swallow too.

      Speaking as a former waiter, I know that a good deal of a waiter's time is taken up by simply checking on fluid levels. And that some people will have a full glass of beer/water/whatever for 10 minutes, but then drain the entire glass in 60 seconds. Quite difficult to time that refill.

      If the waiter no longer had to constantly monitor drinks, it would free them up to handle more customers and/or provide better service.

    You don't want another drink, but your glass/table has ordered you another one, and teh waiter brings it over???
    and then proceeds to add the drink to the bill even though you didn't drink it, but you did order it.?

      Well, common sense tells me that the sensor will signal your server, who will come over and ask if anyone wants another drink. Just because it's RFID doesn't mean it has to be complicated, or track you, or infringe your freedoms, or take money out of your wallet.

      I'm sure the restraunts that (will) use this technology will have thought of that. It will probably only signal a waiter and the waiter will ask if you want another glass. I thought the members a "news for nerds" site would be a little smarter. Common'!

    Is it REALLY that hard to just walk around and look at peoples' glasses?

    Yes, ideally, someday, we can all just lay around half conscious, being tended to by robots. It'll be great, because robots are NEAT!

    RFID tags are only as evil as those who use them. Just because your beer glass has an RFID tag in it does NOT mean you need a tin-foil hat to go to the bar.

    You know, you coudl complain just as much about 802.11 and Bluetooth, because they can be used in similar ways with a little effort.

    Monitor the general vicinity of your laptop? Record what store security systems your PDA enters? Hell, triangulate your cel phone signal (and now GPS it), a wireless electronic item quite personally associated with you by a corporate entity, nonetheless.

    Please TFY next time. That's "Think For Yourself", and I think it should become as popular as "IANAL" and "RTFA" here on "/."

    (Sorry if this was a joke, but the first thing I thought of when I read this article is "Great, another RFID bitchfest")

    Not sure if this is just a Banks' (Midlands-based brewery) thing or if it's law, but staff in Banks' pubs are trained to give you a fresh glass each time, never refill on health&safety grounds.

  7. RFID by Pompatus · · Score: 3, Insightful

    I'd be willing to bet you would have to wait just as long for a refil, since your waiter is most likely responsible for more than just your empty beer glass. The wait time is not due to not noticing, it is due to being in a queue.

    A friend of mine is a bartender. It takes me forever to get a refill if his bar is busy, because he knows I'm not going to get mad at him if I have to wait an extra five minutes to get a drink. (and of course, I will be understanding of the extra wait time because an entire evening of drinking costs me $20 with an included $12 tip)

    Mitsubishi has created something here that would make for a totally cool geek's page and a really neat thing to find in a few offbeat pubs. Nothing wrong with Mitsubishi patenting such an invention, but the problem is that this thing is destined for the conglomerate-sized markets only. You are not going to find this in a place with any kind of unique character to it, you're only going to find it in yellow and orange plastic-table megarestaurant chains. You'll only see it in the kinds of places where turnover is high and the waitresses have to wear a certain amount of "flair", because those are the only places that will be able to afford ordering 180 of these systems to place in their eastern seaboard chain. In these kinds of places, it's going to be about as cool as the LED reader boards in the drive-through that show you what the teenager on the other side of the inaudible squawk box has punched in to the register. Wireless empty glass detectors and LED reader boards to reduce screwing up your order are alright, but they often seem to wind up being applied to things that have suckage at their cores.

    Like the RFID, that only solves the minor problem - making sure the waitstaff notice that your beer is empty.

    The second problem is having them care, which as you point out, is better solved with low-tech. If the waitstaff doesn't know you (e.g. hopefully just doesn't realize you tip well), it's usually better to pay in cash and tip for each round. At least in the US, a lot of people who run a tab on a card suck at calculating proper tips, and usually skimp.

    I've never had a hard time getting timely drinks at places I drank often. But then, I understand that my waiter or waitress depends on me and the other customers to provide them a proper salary for the quality of their service.
