Some older devices may require a particular app to read QR codes — these apps are readily available on the Apple App Store and Google Play. Attackers can embed malicious URLs containing custom malware into a QR code which could then exfiltrate data from a mobile device when scanned. It is also possible to embed a malicious URL into a QR code that directs to a phishing site, where unsuspecting users could disclose personal or financial information.
Because humans cannot read QR codes, it is easy for attackers to alter a QR code to point to an alternative resource without being detected. Aside from opening a website, these actions can include adding contacts or composing emails. This element of surprise can make QR code security threats especially problematic. A typical attack involves placing malicious QR codes in public, sometimes covering up legitimate QR codes.
Unsuspecting users who scan the code are taken to a malicious web page which could host an exploit kit, leading to device compromise or a spoofed login page to steal user credentials.

It then groups grid squares to create larger patterns. QR codes can be used for multiple purposes, but there are four widely accepted versions of QR codes.
The version used determines how data can be stored and is called the "input mode. The type of mode is communicated via the version information field in the QR code. There are two additional modes which are modifications of the other types:. It is possible to create QR codes in many different shapes and styles, but five types are most commonly found.
