@lupyuen I have an RFID tag that was used by the military for similar purposes but these were put on personal lockboxes. I can't post a picture of it but they were effective for keeping track of items.

NFC was already being used with some passports. Airlines are the last to adopt any reasonable technology. (They need to handle any personal electronics for security reasons.)

I will never fly on an airliner if there is any other option. I remember when an airliner carried the original SARS to the USA. I remember when COVID-19 came the same way, mutated to be more deadly and returned to the country of origin before anyone realized it.
