I simply could not resist posting something about what I consider to be the coolest trackable on the planet. KJWX, a cacher based in New Zealand, a few months ago became the first person to have a trackable implant! (The Mark of The Geocacher ((TB60ZG6))) The small chip that uses the NFC technology is embedded under the skin of her hand. In order to log it you need a smartphone that supports the NFC system such as an android, blackberry, windows phone and FIMALLY (thanks Apple for joining the party eventually) the iPhone 6. By placing the phone against her hand you will be able to get the tracking code necessary to log it!
For more info about this futuristic TB check out the blog at It’s Not About The Numbers which she maintains together with her brother.
I hereby challenge the only geocacher / blogger based in NZ that I know, travelgypsynz, to go seek out this TB and log it… you have to do it, if only to see on geocaching that you have discover the TB “in the hands” of the owner! 🙂
