QR ID is an app that allows you to define your unique identity code and then use it to scan as QR code on any other app that supports QR code scanning for identifying users. This app also allows users to add other QR ID codes that they may have on various applications besides the unique identity code. Each QR ID supported from this app can be configured to generate static QR code or dynamic QR codes images which will change every 15 secs. The dynamic QR code provides additional security so that the QR image once expired cannot be reused as long as the scanning apps support handling of the dynamic code.
