Satellites track Mexico kidnap victims?

I’m trying to figure out what’s up with this story… People are getting kidnapped – got that part, so they’re getting RFID chips implanted… which helps how? Snippet from the article

The chips cost $4,000 plus an annual fee of $2,200….

Xega, based in the central Mexican city of Quererato, designed global positioning systems to track stolen vehicles until a company owner was kidnapped in broad daylight in 2001. Frustrated by his powerlessness to call for help, the company adapted the technology to track stolen people.

Most people get the chips injected into their arms between the skin and muscle where they cannot be seen. Customers who fear they are being kidnapped press a panic button on an external device to alert Xega which then calls the police.

“Before, they only kidnapped key, well-known economically successful people like industrialists and landowners. Now they are kidnapping people from the middle class,” said Sergio Galvan, Xega’s commercial director.

…Xega sees kidnapping as a growth industry and is planning to expand its services next year to Brazil, Colombia and Venezuela.

How does a RFID chip help at all? If you’re going to get kidnapped you need some other device that you have with, once your kidnapped then what? Do kidnappers allow you to keep this other device? Are their RFID readers all over the place in Mexico for a system like to to work.

Anyone know or have some guesses?
