QR Codes

Create, manage and use QR codes

What is a QR code?

A QR code is a type of barcode that can be read easily by a digital device and which stores information as a series of pixels in a square-shaped grid. The data stored in a QR code can include website URLs, phone numbers, or up to 4,000 characters of text. A user accesses the information by scanning the QR code with their smartphone camera or a dedicated app.

Are QR Codes safe?

There are security risks associated with QR codes, such as hackers creating malicious QR codes which send users to fake websites that capture their personal data such as login credentials. This is why mobile users should only scan codes that come from a trusted sender such as the University or the NHS, look for an official logo, and when in doubt type the link out in full.
