What Is a QR code?

A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of industry due to its fast readability and comparatively large storage capacity. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be made up of any kind of data (e.g. binary, alphanumeric, or Kanji symbols)

Created by Toyota subsidiary Denso Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes. The QR code was designed to allow its contents to be decoded at high speed.

The technology has seen frequent use in Japan and South Korea; the United Kingdom is the seventh-largest national consumer of QR codes.

QR codes are practically everywhere in Japan nowadays, but here’s a unique take on the technology: the gravestone makers recently announced plans to begin selling gravestones with the two-dimensional bar codes embedded into them.

By simply snapping a shot of the tag with their cellphones, visitors will be able to view photos, videos and other information about the deceased. The device would also keep a log of each time the code was scanned so family members can keep up to date with when other relatives last visited the site.

A QR code on the headstone acts as a link which enables users of smart phones and mobile tablets to scan and automatically connect to a personalized website. It can be viewed on the phone or mobile tablet as visitors wander through the cemetery or by simply typing in a unique web address into your computer internet browser.
