Why Should I Use a QR Code?

QR Codes, 2-d barcodes

They’re practically an epidemic.

Every since Smartphones hit the market, QR Codes have multiplied exponentially as a vital component of every self-respecting advertisement, product or company and have recently even began to appear on most people’s business cards.

One of the main elements that has contributed to the QR Code’s great success is the remarkable versatility that it offers its users. The QR Code can redirect its scanner to a website, a specific location on a map, a video or song, a Facebook profile page, can create a contact in your address book or even call a specific number.When you create a QR Code, you have the freedom to break out of the mundane, banal crowd and advertise your product in an original, approachable manner that is the most suitable for your product, in a way that enhances its advantages. Although QR Codes look like an innocuous cluster of black and white dots, they have the potential to raise your product or company to a higher level of awareness, accessibility and success.
