Retailer uses 3D QR codes and the Sun to time limit discounts
- yogrish 14y agoAppears to me that Koreans are fighting a lot in Retail space. Earlier, Tesco (Home+ in Korea) launched Virtual Grocery store which is a big hit. Now its competitor came up with this innovative idea. More innovations in pipeline ;)
- olliesaunders 14y agoThe 2D (virtual) shop you are referring to: http://www.telegraph.co.uk/technology/mobile-phones/8601147/Tesco-builds-virtual-shops-for-Korean-commuters.html http://www.telegraph.co.uk/technology/mobile-phones/8601147/...
- asmithmd1 14y agoThat is awesome. Does anyone know if Peapod, Fresh Direct, or any other US based grocery delivery service has a API? I want to try something like this.
- m_for_monkey 14y agoI remembered this story as a fake. Now I researched a bit and found out that this video really was just an advert concept, but later they made it real. http://www.tescoplc.com/index.asp?pageid=17&newsid=345 http://www.tescoplc.com/index.asp?pageid=17&newsid=345
- 6ren 14y ago> there is no need to wait in to collect them. Fast, asynchronous delivery is part of the puzzle. Waiting around for amazon deliveries is a pain; but for low-value groceries, the risk of theft isn't as serious. It works OK for newspaper deliveries, and when I was a kid we had milk deliveries left outside the door with no problems (yes, horse-drawn).
- Dn_Ab 14y agoThis service would be even more awesome with self driving vans optimizing logistics. Now to solve the delivery from van to door problem - as usual the last 1% takes as much effort as the previous 99%.
- j-b 14y agoThat's an interesting idea. I'm coding Direct Store Delivery software that manages inventory through wireless handheld devices. The problem is that a lot of shipping is from vendor to store directly and the receivers are required to validate the shipment has the correct products, quantity, cost/deal invoice details and then work it out with the vendor delivery driver as needed. There are companies that strategically attempt to offload certain products that the store doesn't want at that point in time but will save the vendor $ if they can ship today vs. next week when different cost/deals take effect.
- Digit-Al 14y agoI wonder if you could hack it with a spotlight?
- olliesaunders 14y agoAnd a black sheet to block sunlight
- JonnieCache 14y agoOr with a kinect.
- digitalsushi 14y agoYou could just take a photo of the sculpture and paint it on your phone with a cheap editing app. You would just need to infer the shadow areas and paint them black, and the sunny parts white squares. QR codes were made to be very resilient to noise, and I can attest that you can mess with them quite a bit before they won't decipher. My boss asked me to take a QR code linking to our website and to try and rearrange some of the squares to be our initials. I got a few to work, and learned that the Reed Solomon encoding duplicates the data so much that this egregious manipulation was still acceptable.
- garethadams 14y agoOf course by doing this, you remove some of the error correction. Your mutated QR code is less likely to be scanned by a camera which is lo-res, at an angle, in dim light or affected by some other imperfection. People who test customised QR codes almost certainly only test them under close-to-perfect conditions.
- digitalsushi 14y agoNope. My test conditions were transferring them to a black t-shirt with an iron-on printer sheet, and then taking a jpeg of my wife wearing it in the kitchen with an iphone and using a QR code recoder app.
- wiradikusuma 14y agoa statue is a permanent installation right? how do they prevent one guy scanning it and sharing the URL(?) to everyone? or just bookmark the url and open it again next day without scanning the statue again.
- poundy 14y agoTech-minded guys think of all these issues. It is a brilliant marketing idea! I would scan the QR code.
- DavidSJ 14y agoMaybe they'd like for one guy to share the URL with everyone.
- altrego99 14y agoYeah - I guess this is more of a customer attraction and branding scheme than foolproof.
- tytso 14y agoI assume it goes to a URL which is only valid between noon and 1pm. The QR code is probably scannable during a time period slightly wider than that, depending on the time of year. It looks like the QR "statue" pivots to correct for the changing path of the sun across the sky, but the positioning doesn't have to be accurate to the point of working exactly from 12:00:00 to 13:00:00 local time. You can also add enforcement on the web server.
- mokus 14y agoYou can actually just play the video on the linked article, pause it at the right time, and point your phone at the screen. If I could read Korean I might be able to tell if the site has a time-lock of some kind. This isn't really about being secure - it's about clever marketing. And it definitely succeeds at that.
- altrego99 14y agoIt will be an interesting challenge to write a program that can 'scan' the QR code at all time.
- capex 14y agoKorea must enjoy fine sunny mornings I presume..
- techiferous 14y agoVery creative. I would expect the biggest win for this campaign to be in the very beginning when the novelty attracts people. I don't think this would be sustainable, because the QR code sculptures would require continual adjustment throughout the year to account for the procession of the sun. And clouds.
- TazeTSchnitzel 14y agoCouldn't you just change the sculpture's orientation? Or is it more subtle than that?
- xcallmejudasx 14y agoHow difficult would it be to have the sculpture on a lockable swivel? Every month or so you just go out, realign it, and lock it back in place.
- jws 14y agoAt 1:09 in the video you can see the sculpture get pivoted on a horizontal axle. That is sufficient. At some point during the day (near noon if it faces south) the left/right alignment will be correct, at that point you can tip it on the axle for optimum legibility. The angle will vary by season, but if it is legible for an hour a day, there is a fair degree of slop available. It should be intuitively human adjustable, simply maximize the square pixelation nature, or if you want something more explicit, make the bottoms of the long vertical dark spots line up with adjacent short vertical dark spots. It is near June and they appear to be vertical. In the winter, with a lower sun, it will need to be tipped down and people will need to hold their phones lower and perhaps come closer. Good thing they didn't build it like this for winter. Then in the summer people would have to sit on a friend's shoulders to take the pictures.
- joelhaasnoot 14y agoI think it's a win/win situation not just because of PR but also PR during the quietest hour. Foot traffic helps in retail.
- mertd 14y agoSo if you increase sales during certain hours, does that mean you make some sales that you otherwise would not have made or are you just shifting customers around different time slots?
- URSpider94 14y agoI'm sure it's a little of both. Sounds like they recruited a lot of new email subscribers, which is valuable. But, even shifting demand can be good if you can level out demand -- may mean fewer staff at peak times, shorter delivery queues, etc.

- Toenex 14y agoVery cool. A variation on this might be the create a QR code that can only be seen from a particular orientation - a bit like the 4 on the UK TV Channel 4 interludes. You could use it to ensure people were looking in the right direction or perhaps or at the right thing.
- TazeTSchnitzel 14y agoOne of the Channel 4 logos in question, for non-Brits: http://www.youtube.com/watch?v=R94X1M7r1SU http://www.youtube.com/watch?v=R94X1M7r1SU
- sp332 14y agoHere's the April Fool's version, where they removed the CGI effects from the video https://www.youtube.com/watch?v=tEgmhwP7XWc https://www.youtube.com/watch?v=tEgmhwP7XWc :)
- TazeTSchnitzel 14y agoOh that's clever. Although it's less of an April Fool, more of an April prank.
- scoot 14y agoThis one might be easier to follow for those not familiar with the shape of the logo: http://www.youtube.com/watch?feature=endscreen&NR=1&v=ix_WsF7K3UQ http://www.youtube.com/watch?feature=endscreen&NR=1&...
- nsns 14y agoIMO this is a PR move, meant to garner publicity, but not really workable. The sun changes positions throughout the year, then there are clouds, it doesn't make sense.
- maybird 14y ago"Sorry, offer not available in Seattle." ;)
- ecocentrik 14y agoIt would require hard shadows... since clouds defuse light resulting in soft shadows it wouldn't work if there are any clouds covering the sun.
- vecinu 14y agoWhile this is true and will most likely not work for all businesses attempting to gain publicity, they could always pivot the QR code to adjust for the sun's position and/or clouds.
- jasonlotito 14y ago> As a result of its creative promotion, Emart reportedly saw membership increase by 58 percent in February over the previous month, they also observed a 25 percent increase in sales during lunch hours. Yeah, so they pretty much come out and say it's a PR move. And is workable, apparently. As for the issues you suggest: > The sun changes positions throughout the year So does the sculpture.
- biot 14y agoIt would be interesting to hack this and augment the sculpture to produce a URL under your own control. By changing the heights of the various protrusions, you could alter the shadows and thereby alter the code. Hopefully someone would be able to do this in an easy to reverse manner by taping on foam pieces rather than literally hacking pieces off.
- MrEnigma 14y agoThe box on the delivery made has some questionable spelling on it. There is a Team America joke in here somewhere. http://i.imgur.com/BG7mxl.jpg http://i.imgur.com/BG7mxl.jpg
- artursapek 14y agoWhen I read the headline I thought I was going to see a QR code printed in UV-sensitive ink. This is much more creative. Like people have said though, this probably isn't as maintainable as a UV-sensitive one might have been.
- joejohnson 14y agoThis is very clever. Of course, they will need to move the signs slightly every day, as the alignment of the 12-1 o'clock hour will change with the seasons. Also, what's preventing someone from taking a picture at the proper time and posting that photo on the internet?
- jrockway 14y agoThe article, in fact, does this. So nothing. It's just an ad.
- javajosh 14y agoImpressive. But you know what would be more impressive? Build a sculpture that yields different, valid QR codes in every season.
- shabble 14y agoFor a more technological solution to the copied image problem, and also the reorientation necessary throughout the year, I think you could perhaps build a very large Pin Grid[1], with actuators for each pin, able to extend or retract them to the required position. Then you can figure out different patterns which are valid when lit from a particular direction, as well as altering the actual data it encodes, synchronised with updating the coupon code that merchants will accept. Could be kinda pricey for that number of actuators though, but if you were willing to have very slow update frequency, a single 2-axis adjustment head (think plotter or laser-cutter) with a smaller number of push/pull elements could move around, changing only X pins at a time, maybe with a friction lock to stop them moving once it progresses onto the next group.
