If so, what is required to do so?

If by chipboard you mean particle board, or a wood-like product made from combining woodchips and sawdust with special resins, then the answer is yes, it is possible—but it would require a special tag.

If you took an ordinary RFID label and tried to embed it into chipboard, the process of making that chipboard might damage the tag. And the moisture in the wood chips would likely detune the RFID transponder's antenna, as well as absorb some of the RF energy from the reader, assuming you were using an ultrahigh-frequency (UHF) tag. (Water absorbs RF energy in the UHF range.)

To embed an RFID transponder in chipboard, you would likely require a special transponder protected from damage during the manufacturing process. You might also need to tune the antenna to work in close proximity to the wood and resin. Companies such as Avery Dennison, NXP Semiconductors and UPM RFID, which manufacture chips or transponders, can help prototype antenna designs to achieve optimal performance.
