QR Code stand for “Quick Response Code” and is just a 2 dimensional code similar to a bar code.
We all know that bar codes are scanned at the grocery store at check-out time to speed the process of calculating our total bill. What sets QR Codes apart from bar codes is that bar codes are usually linked to a database that the scanning device pulls information from (price, name, etc.) whereas QR Codes actually contain information. QR Codes do not need to pull data from a database because the information is embedded within the code.
What can you store in a QR Code?
What type of information can be contained in a QR Code? Well, just about anything; however, there is a limit to the amount of characters you can store in a QR Code.
You can store up to 4,296 alpha-numeric characters in a QR Code
Most people will choose to use a QR Code to store text and numbers and with 4,296 characters available you have a lot of flexibility.
Why should I care about QR Codes?
You should care about QR codes if you want an easy way to share information with people! How many times have you seen an advertisement and wanted to remember the information for later, but didn’t have time to write it down? Someone gives you a business card and while you have good intentions of adding the information to your contacts you never get around to it and end up losing the card! As a business owner you may want clients to visit your website; however, how do you expect them to remember the address? What if your website address ends in .org, .co, .net, .me or anything else except .com – even if people get the first part of your URL correct they can still end up in the wrong location if they don’t have the ending right.
With a QR Code these challenges all go away. A person can use their smartphone and installed scanner application to scan your code and be taken to your website, add your contact information to their contacts, and even add an event to their calendar!
What do I need to use QR Codes
To use QR Codes you first need to have a QR Code generator. The QR Code generator will create the QR Code for you and once you have the code you can put it on your business card, print advertising, agendas, etc. I have a free QR Code generator here. Once you have a QR Code you will need a smartphone and an application that can read bar codes. I’ll compile a list of apps for your smartphone in a future post.
