DYNAMIC QUICK RESPONSE (QR) CODE WITH EMBEDDED MONITORING DATA FOR EASE OF MOBILE ACCESS

摘要

A method and a system for monitoring at least one parameter by a monitoring device 20 are disclosed. The monitoring device 20 comprises a graphical LCD display unit 22, at least one QR code 24, and/or keys 26. The at least QR code is displayed in the LCD display unit 22. The parameter (12, 12a) is embedded in the QR code 24. The monitoring device 20 dynamically generates the QR code 24 with the change of the parameter (12, 12a). A mobile/handheld device 28 is used to scan and decode each of the dynamically generated QR code 24 to extract data about the at least one parameter. With the data dynamically updating, a user has to be physically in front of the monitoring device 20, thereby ensuring the security of the monitoring device 20. When the mobile device 28 is connected to the other devices 30, a computer 32, and a cloud server 34, the processing of the data related to the parameter is processed by these connected devices, thereby reducing the processing burden on the monitoring device 20 and the mobile device 28.
