Think twice before scanning a QR code — it could lead to identity theft, FTC warns

Scanning a QR code can expose you to identity theft, according to the Federal Trade Commission. 

QR codes, which store links and other information and which are readable by a smartphone camera, are today widely used at businesses including restaurants and a range of different retailers. Over 94 million consumers will use their phone to scan a QR code this year, according to Insider Intelligence. 

The technology helps retailers by giving them insights into customer behavior, such as by linking a QR code to a store loyalty program. Yet while they offer a measure of convenience for customers and help enterprises do business, they can also give bad actors a stealthy tool for stealing consumers' personal information, the government watchdog warns.
