What can a QR Code do?
A lot of people don't know this, but QR Codes are actually old technology. The QR code system was invented in 1994 by Toyota's subsidiary, Denso Wave. Its purpose was to track vehicles during manufacture; it was designed to allow high-speed component scanning. With the advent of the smart phone and the capability of such devices to easily read and process these barcodes anywhere, at any time, their potential and use began to blossom.
A QR code is literally a bridge to connect the "real world" with the "digital world." You can't put "Click here" on a t-shirt or printed brochure, but a QR code gives you virtually the same benefit. "Scan here" and visit the online destination of my choosing. Basically, anywhere a website button could take you, a QR code can bring you to the same place.
We often generate QR Codes for our clients to place on cards, ads, stickers, or T-Shirts. It can store text, a URL, contact information, phone numbers, SMS whatever. I have used them to link directly to websites, Facebook pages, and even PayPal payment screens.
The possibilities are endless.
