Applied Digital Solutions (ADS), which has already developed a chip that allows medical records to be implanted under a person's skin, says it is now ready to move to the next stage of developing the ultimate onboard tracking system.
A spokesman said that, if the market demands an implanted Global Positioning Satellite (GPS) device, for example to keep tabs on kidnap victims, the company will be able to provide it.
He confirmed that ADS is starting to develop and test such products, even though it had not been given the nod from medical authorities to test them on live subjects.
"There seems to be a pressing need for this kind of product to stem the tide of kidnappings in Latin America. So we're very interested in responding to this demand and helping to save lives," the spokesman said.
The technology has been touted as a way for western governments to adopt national ID cards. Adapting it to track using GPS is not difficult, he explained.
