Description

Technical Field

[0001] The present invention relates to a body temperature collection technology, and in particular to a body temperature collection card with NFC communication function and a body temperature collection method. Background Art

[0002] Using a handheld thermometer to measure temperature requires a certain amount of waiting time, which can easily cause congestion when multiple people pass by. In addition, in school and enterprise scenarios, if you want to register the real-time temperature of a specific person, you can only use a third-party input device (such as a temperature measuring device with a connectable card reader. After the forehead thermometer is connected to the card reader to read the person's identity card information, the corresponding temperature measurement data of the forehead thermometer is transmitted to the background) or directly record on paper and then import it. This is prone to human errors, and the input time is longer than the measurement time, which aggravates the congestion.

[0003] Facial recognition access control based on thermal imaging is relatively expensive and is more commonly used by large enterprises or government departments, but is unaffordable for small and medium-sized enterprises and industrial parks. Summary of the invention
