What Is a QR code?

A QR code (short for Quick Response) is a two-dimensional barcode designed for storing data under 100KB in size. Since it’s easy for smartphones to read this type of information through their camera, these codes are used frequently for marketing, event check-ins, and other types of data entry.

Are QR Codes Secure?

The short answer is yes – as long as you’re using a secure QR code scanning app. When scanned, the QR code will direct the user to the website or information that has been encoded within it. This makes it difficult for someone to tamper with the data without it being noticed. However, if you’re using an unsecured QR code scanning app, then there’s a chance that someone could intercept the data before it reaches your website. For this reason, it’s always important to use a reputable and reliable QR code scanning app.
