What Information Does a QR Code Contain?
QR codes are actually barcodes using cryptology. So there is no information in sight. Only when the QR code is decoded, information is available at the destination address. In addition, the codes are standard in appearance. In other words, the differences are not easily understood unless you look carefully. The code reader, on the other hand, examines down to the smallest detail, decodes the code and routes it to the correct address.
