This idea was conceived during the COVID times. People used to forget wearing mask before leaving the house. To remind them to wear a mask, one of the ideas was to attach a RFId sticker to the mask. By placing RFId detectors along with PIR sensors to sense movement, the unit can give an alarm if there is movement & it is not able to detect mask RFId.
The same concept can be extended to manufacturing industries. If there is a hazardous region where protective gear has to be worn mandatorily, we can have a RFId sticker on the protective gear & instal a detector near the hazardous area. If the protective gear is not detected, it can give an alarm.
If given an oppurtunity, we can work on this concept & realize a product.
Thanks.
