This week I made possibly the geekiest thing ever. It is a deck of cards that are marked on the back. They aren’t marked by traditional tiny hidden markings on the corners however, the entire back of the card is marked by a QR code.
A QR code is a type of bar-code that is commonly scanned by mobile phones to exchange contact information, urls or as is the case here, text.
If you want to see what card lies face down on the table, you get out your mobile phone, launch your favourite bar-code scanning app, point the camera on the back of the card and then you will get a message stating the exact name of the card.
Want to try it? Get out your phone and see if you can use it decipher the cards below.

This is genuinely awesome! I love geeky things like this. Whether they could actually be used in a trick without the punter working out what was going on is another matter!
If you slapped on bluetooth my little geeky mind would exploded hehe,
These card are outstanding, will you be selling them at all?
Love

@Louise Yes, correct!
Lovely, yet useless. You need your phone to read it. Who’s gonna whip his/her phone out to read these babies?
If that would have been the point, you should’ve invented your own code which would have been a little more invisible.
Pure win.
Pure want!
Cool. Did you print them out somehow, or order them through a service? They look like they’re made of something rigid like a real playing card. Nice novelty either way!
Pretty good bet these will never be used in Reno or Vegas
Absolutely brill!!!
I want some. You should sell them. Please!
that’s fucking cool
