Re: [aroid-l] Stolen cycads - microchips

Jim et al,

About 4-5 years ago a number of large and very rare cycad specimens were 
utilized in the Chelsea flower show. These all came from S. African boatnical 
gardens, and were specially tagged with miniature radio frequency (RF) 
transponders injected in their woody stems which served as identifiers. They 
could be used for tracking to a limited extent, if the specimens were somehow 
stolen in transit or even at the show itself. This technology has advanced 
rapidly with increased miniaturization and many new applications have been 
developed. I don't know how useful these RF transponders would be with 
herbaceous material, but the woody tissue in cycads, and their characteristic 
slow growth make the use of this technology much more promising. As Jim 
mentioned, similar devices have been used for some years in animals, and you 
can even have your beloved pet injected with a RF chip. The transponders do 
have a life span but will remain active for many years and since they can be 
programmed with unique identifiers and other data, they are useful for 
specialized identification, security, etc. There has been some talk about 
using these devices injected in people for various purposes, and lately with 
Homeland Security a great many of these and similar technologies are being 
explored. This scenario always inflames civil liberties activists with good
