Loved up and clued in

摘要

The apple of your eye always has their eyes on their Apple -iPhone that is. So how to get their attention? Here's a simple way to impress your Valentine: a techy QR code treasure hunt. These 2D barcodes can store masses of data, from texts to web links, email addresses, even geographic coordinates. All your sweetheart needs is an app that reads QR codes. To get started, search for a QR code generator online to create your clues. QR codes can be read in any orientation and the built-in error correction means different colours and styles scan just fine. In fact, they can be rendered in almost any material, from collage to cake. There's even a firm that prints QR codes on chocolate -for a twist on a Valentine's day classic, order a box of edible clues. I've cross-stitched a QR code before - turning a clue into a keepsake.
