Embeddable in-metal RFID

Embeddable in-metal RFID

Embeddable in-metal RFID

(OP)
I am new to RFID but relatively familiar with how it works and its limitations. However, I recently learned of an advancement in the tech known as embeddable in-metal RFID, which appears to be a newer evolution in the tech and a product offered by very few suppliers thus far. I believe this type of RFID may address a problem I've been trying to solve for some time - unfortunately there seems to be very little information available on the web.

So can anyone here explain this evolution in RFID tech to me? How exactly do these readers/tags penetrate metal? Is there a limit to the thickness of the metal material the tag or reader is embedded in? What are the drawbacks of this type of system vs the standard LF/HF systems that cannot send/receive signals through metal?

If you happen to live near Dallas, Xerafy has their US Office there.

If you place antennas inside metal, they won't work in general. So antennas inside metal may be a marketing item only. Unless skin depth (look for skin depth calculators vis google) allows some energy into the antenna and the antenna looks like a transformer, as in this link;http://telaeris.com/2012/04/embedding-rfid-in-meta...
