What is QR code?

These black and white squares have taken over the world, but what is their purpose?

By Joao Lima

QR code, or quick response code, is a 2D barcode in the form of a square which contains several smaller black and white squares. It is like a new version of a barcode.

These QR codes are only readable when using a device, such as mobile phones or tablets, and other QR code reading devices.

Usually to use the system, consumers can simply download a reader app from their app store.

Once the code has been scanned, users will be directed to a page with information regarding a service, product, area, etc.

QR codes are one of the most important marketing tools of today, as they allow marketers to engage people with a business by letting them scan and then redirect them to a specific online page.

QR codes are being now used all over the world and are embedded in many everyday objects and even landscapes.

For example, in Lisbon, Portugal, QR codes have been literally built into the streets’ Portuguese Pavement using black and white stones, which have been used to “draw” lines, figures and others since the 16th century.
