They mean digestible.

"The tag system outlined in the patent includes a tag comprised of at 
least one antenna <javascript:OpenGlossary("antenna");>—which could be 
made of digestible material such as encapsulated metallic liquids, 
clays, or even liquids or gases—and an external transceiver 
<javascript:OpenGlossary("transceiver");> that communicates with the tag 
to read <javascript:OpenGlossary("read");> the RF signals. The tag would 
document when a pill was digested because its antenna would also have 
been broken down at the same time, thus destroying the tag's ability to 
receive and transmit an RF signal."

BTW "Electronic Article Surveillance", as used in Kmart, is based on 
different technology (typically 58Khz signal), and would not be affected 
by RFID.
