The Barcode Revolution: Welcome To Our Automated World

January 8, 2020 by 25 Comments

Featured in many sci-fi stories as a quicker, more efficient way to record and transfer information, barcodes are both extremely commonplace today, and still amazingly poorly understood by many. Originally designed as a way to allow for increased automation by allowing computer systems to scan a code with information about the item it labels, its potential as an information carrier is becoming ever more popular.

Without the tagging ability of barcodes (and their close cousin: RFID tags), much of today’s modern world would grind to a halt. The automated sorting and delivery systems for mail and parcels, entire inventory management systems, the tracing of critical avionics and rocketry components around the globe, as well as seemingly mundane but widely utilized rapid checkout at the supermarket, all depends on some variety of barcodes.

Join me on a trip through the past, present and future of the humble barcode.

Homemade Bokode

We’ve recently been getting a lot of new comments on our Bokode post from a while back, and with good reason.  [M@] has managed to find a way to replicate Bokode at home, using $0 worth of equipment (before the price of microprint). To accomplish Bokode at home, it seems all you need is and old webcam lens assembly and an LED.  Of course the his version is not as thin as a regular barcode so it probably wont be replacing anything in the near future, but the concept of from MIT to home within such a short period of time is amazing.

Bokode, A New Barcode

The MIT Camera Culture Group utilized Bokeh, an effect where the lens is purposely placed out of focus, in order to vastly improve current 2D barcode technology. Dubbed Bokode, the team claims that an off the shelf camera can read data 2.5 microns from a distance of over 4 meters, compared to today’s average barcode reader’s maximum distance of only a foot or so. What looks most interesting is the ability to produce a smoother and more accurate distance and angle calculations (relative to the camera): allowing for a better augmented reality. It also seems to be more secure than traditional 2D barcodes, that is of course until the hacker community gets a hold of it.
