Do RFIDs constantly track? Answered

I'm wanting to buy some RFID tags for a project that I'm doing, and I'm wondering if passive RFID tags that are activated constantly track and  send their location to the RFID receiver.  This is absolutely critical to my project.If these don't, what can I use that does the desired function?  Thank you so much!

Radio-Frequency IDentification = (RFID)

Does not
locate, but the range is often short and I F the trackers want to they
could broadcast their location which would give you an idea of the
nearabouts of your RFID tag.

UPS was working on a chip that would be slapped on a package and track its delivery journey by GPS. It would work because UPS trucks have a translucent non-metal roof to facilitate satellite signals.

Passive RFIDs do not have power supplies. They work by "harvesting" power from the RFID tracker when it sends out a signal, and use that power to send back their reply.

If you want some sort of active "I am here" broadcast, then RFID is probably not the right technology.

Passive RFID's do not track or send their location. They only work within a couple inches of the reader and all they send is a number. What you're looking for is a GPS tracker.
