I was in Japan a couple of months back, and everywhere I went were these things called 'QR Codes'.
They are much like barcodes, but are a 2-dimensional bitmap that holds encoded information that is designed to be read with a reader such as a mobile phone's camera. Uses for the codes are for holding text messages, urls, or phone numbers.
Now, I've only seen them in Japan, and had forgotten about them until I stumbled upon one online, and then I downloaded the reader software for my phone, and I've been playing with a QR Code generator online to make different things.
I was wondering, has anyone seen them kicking out and about in this country?
