It’s a crossword! It’s a design! No it’s a QR code!

What is a QR code?
A QR code is short for “Quick Response code”. This is a group of black and white squares which have to be scanned for information like addresses, images, messages, and YouTube links.

These nifty patterns seem to be popping up everywhere. You will see them in grocery stores, bathroom stalls, on movie tickets, and even as treasure hunt clues at birthday parties. These are 2D, or 2 dimensional, and store information horizontally and vertically so they can pack more in than we can on barcodes.

Reminder: Barcodes are the vertical lines (one dimensional and directional) that we see on anything we buy from a supermarket. These can store only upto 20 characters (letters and numbers).

Where did QR codes come from?
Denso Wave Inc, a Japanese company, invented the QR code in 1994 as people wanted to pack in more information on the code.
