I understand these have been in use for a while but was curious and looked into it and thought others here may be curious as well or may not have noticed at all. The image below is the front and back of one I ripped off a package from Ama$on that UPS delivered..The link at the bottom is a post from a guy in WA state that really got into it in March of 2023.
Very interesting though I am completely ignorant on these chips and RFID. How does it get it's power? What is it connecting to or is it just used with its antennas to be connect to?
RFID labels get power in two main ways: Passive tags harvest energy from the reader's radio waves to activate and transmit data (no battery needed), while Active tags use their own internal battery for longer range and more powerful signals, making them bulkier and costlier. Passive tags are common for items like key cards or clothing, using inductive coupling to power up, whereas active tags track vehicles or large shipments.
