What Is A QR Code?
A QR code, abbreviated for “Quick Response” Code is a two-dimensional barcode matrix that was originally used for the automotive industry. These codes have actually been around for years, first originating in Japan, but now finding its way into the U.S. Most popularly now, they are used with smartphones for many different purposes and uses. These little squares are very popular because of their ability to store large amounts of data in one single square. The modules in the square are arranged in such a way that will allow each one to be unique.
It was originally created by Toyota to track their vehicles when being manufactured. Its purpose is to not only store a large amount of data, but also for the QR code reader to decode it at high speed. It is also being used in the United Kingdom, with them being the 7th largest consumer of QR codes.
QR codes are designed to store a mass quantity of data, but the amount depends on the version, characters and error correction level. QR codes have many different uses in the world now ranging from marketing, real estate, retail, education, construction and so on. They have become a staple in the United States. I feel like everywhere I go now I see them. The other day I was in the grocery store, I saw one on a bin of apples. If you scanned it, it gave you the nutritional information on the apple!
Here are a few ways in which QR codes are being utilized:
- Transportation: Buses and public transportation are now utilizing QR codes by putting signs up next to the bus stop with QR codes to scan. When scanned, these QR codes tell you the bus route times, if it’s actually on time, and maps of their routes

- Real Estate: Real Estate has also taken a big step in the world of QR codes. These codes are now places in other areas (not just on a for sale sign out on your front lawn) such as conventions and when scanned, they can give you details about the house for sale such as specs, prices, pictures and more!
- Retail: QR codes are making a big hit in the retail world. Everywhere you go there are QR codes for discounts, coupons, product reviews and more! You see them in grocery stores, shopping malls, department stores and even restaurants!

These are just a scraping of what QR codes have to offer in the world. It’s so funny to see a generation that is so dependent on their smartphone. A long time ago, I remember when I was a kid, if I wanted to call my friends to hang out, I had to go home to use the phone or find a payphone. Now, it’s just a simple click of a button or a text message and you are already at your friends house quicker than you could pick up the phone and dial the number. In a world that is ever changing, we must keep up!
