A QR Code Reader is a system and hardware application used to scan Quick Response (QR) Codes. QR Codes are two-dimensional barcodes that can be scanned using a camera, smartphone or tablet. The QR Code Reader decodes the QR Code, allowing users to access the encoded information. The information is typically a web address or text message, but can also contain GPS coordinates, telephone numbers, email addresses, text messages, and more. The QR Code Reader can be used to quickly access the encoded information without manually typing it in. It can be used for a variety of purposes such as marketing campaigns, product information, event tickets, customer loyalty programs, and more.
