Question

Wireless technologies

In addition to the usual intercom, what other technologies for wireless transmission to readers exist?

Answer 1

Skorre not methods, but standards - the method for all is one signal transmission over a radio channel.
Start with https://ru.wikipedia.org/wiki/RFID
usually each standard has its own frequency of tags and therefore its application - the higher the frequency, the more complex and expensive the readers are and the farther they can work (from 50 mm to 5 m)
