QR Codes, Pt. 2: What’s new?

If bar codes represent older technology, why are they a big deal? What has changed?

Essentially, bar codes represent a mid-twentieth century technology. However, there are at least two major developments that make the technology very appealing to public history and interpretation projects.

One development is in the bar codes themselves. There are many different types of bar codes that serve many different functions. QR codes have been around since the mid 1990s, and are widely used in Asia for providing basic
information or entertainment; I encountered my first ones in Singapore and Malaysia in 2003 without knowing what the heck they were. These codes can store a breadth of media; pretty much anything that can be associated with a URL or phone number — or even a specific text or SMS.

A more important development is that of access. Companies are crafting more and more devices (and applications for devices) aimed at individual consumers.  The exclamation “lightning speed!” is not accurate enough to describe this celerity. A quick digression: six years ago, I had a blast – literally –while registering for wedding presents at one major department store. The clerk gave us a code reading “gun” reminiscent of a Star Wars blaster toy I had as a kid (which I quickly pried from Sarah’s hand) that allowed us to point and zap any product and immediately uploading it to our
registry.  We still joke about some of the wacky things I added just for the fun of it.  Now, a special device is not necessary to do this; a consumer only need point their smart phone’s camera at a barcode and it instantly reads and (in the case of some stores) uploads it to a wedding registry. Or a birth registry. Or a birthday registry. You get the picture.

By my rough count, there are hundreds of different applications that the general public can use to personally access bar codes. (I have three on my iPhone now.) Also, the number of people carrying smart phones is growing
