What Are QR Codes?
You’re more than likely familiar with them. They’re the funny-looking square objects you see on items, videos, ads — just about anything.
QR, or Quick Response codes, are similar to the barcodes you see on many products’ packaging. The main difference between the two is that QR codes can hold a lot more data than traditional barcodes.
QR codes can store up to 7089 digits or 4296 characters. That includes punctuation marks and special characters.
It can equally encode words and phrases (e.g. URLs). The more data added to a QR code, the more the size increases, and its structure becomes more complex.
When scanned by a compatible device, including a camera-equipped smartphone, that data is extracted.
What’s nice is that even if it’s damaged, a QR code’s structure data keys include duplications, so it allows up to 30% of the code structure to be damaged without affecting its ability to be scanned. (e.g. coupons, interactive links, etc.)
QR codes use is relatively straightforward. They can be used on your website for numerous purposes; everything from coupons to contact information.
There are two types of QR codes: Static and Dynamic.
A Static QR code is fixed, and you’re not able to edit once the code has been generated. It’s the best code to use for personal use (e.g. access to home WiFi by scanning the QR code).
Dynamic QR code can be edited, updated, and changed however times you need. It’s ideal for ad campaigns, sales, coupons, and more (e.g. share your social media platform on a print ad).
