The Eye-Fi Explore ($130) not only adds 2 GB of memory to a digital camera but also links a camera wirelessly to a Wi-Fi access point—and "geotags" each photo with location data. Geotagging makes it easy to map your travels, though the Explore depends on a database of Wi-Fi access points that largely limits its reach to metro areas. The bulkier ATP Photo Finder ($100) packs a more accurate and wider-reaching GPS receiver.
