QFC, the grocery store closest to me, has those irritating shoppers cards. They try to motivate me to use it with
discounts, but that just makes me want to use a card, I don't care whose card and
I don't care if the data is accurate. They should let me have my data or make it useful to me so that I actually care.
I can imagine several useful tools based on this: automatic grocery lists, recipes using the food you purchased, cheaper alternatives to your purchases, other things you might like based on what you purchased, or integration with dieting websites or software. At any rate, right now all I care about is getting the discount from using a card, but if they made the data available to me then the grocery store could align our interests and I'd want to ensure the data's accuracy.
Checking out at a grocery store to which I rarely go, the cashier asks me if I want an
Albertson's card. I respond sure and she hands me the form on which I give up my personal information. I ask if I need to fill this out now, and she says yeah and it will only take two minutes,
which surprised me because at QFC they just hand me a new card and send me on my way. I fill in my phone number as the first ten digits of pi so I don't have to worry about getting phone calls but
its something I can remember next time I'm there and don't bring the card.
I turn to leave and the cashier asks me is that a '759' or '159' in my phone number. I stop for a second because I only know the digits as a sequence from the start and pause long enough reciting it in my head that its clear its not my phone number. And she calls me out on it: "Is that your real phone number?" I sigh, "No, does it have to be? Are you going to call me?" "Yeah," she says, "I'll call you." (ha ha) "Well I'll try entering this number," she says doubting the computer will accept the fake phone number. "On the number's already registered," she says, "So you already had a card." "No," says the manager who had walked up during for this exchange, "It means someone else used that same number." So the moral of the story is, try your fake phone number before trying to use it to get a new card.
Another use for my new phone is as a replacement for my grocery
card, those little plastic cards with a bar code on them that the grocery store gives you to track your purchasing habits. I've previously gone to great lengths to increase space in my pockets by
removing infrequently used keys and reducing my wallet to the essentials. So I was glad to get rid of the QFC card and replace it with a photo of its bar code on my phone. Since the important part
of the QFC card is the bar code which is just an image of black lines, if your phone has a camera and a screen with a reasonable resolution you can take a photo of the bar code and later display it
to a reader. I've so far been able to try it once and successfully at a normal checkout line, but the reaction from the checkout lady was enough that I may in the future just keep a card in my car.
She was very excited, asked me what kind of phone I had, called over another checkout person and generally made a large fuss. Also the checkout people generally don't mind giving me a new card if I
don't have one with me.
At the grocery store the other day Sarah and I attempted to find shallot for a recipe, but I can't
tell the difference between shallot, sweet onions, yellow onions, etc. etc. We found something that we decided was the closest we'd find in the store and I believe we picked correctly because at
checkout the cashier rang it up as shallot.
I think this could be
a practical problem that the 20q Pocket Mind Reader should be able to solve: obtain the name of an unidentified object. When we got home
I decided to test the 20q Pocket Mind Reader on shallot. Unfortunately, it told me I had an onion, but I think if these were designed for identifying unknown objects based solely on information you
can obtain by looking at it, rather than requiring knowledge of seeds, where it grows, etc. it would do better. Or I could just ask someone who works at the grocery store.
