The silver pendant “A Very Special Heart” holds a USB device listing your medications, allergies, vaccination records—any vital details your doctor or emergency medical personnel might need (with password protection for sensitive information). The PC-compatible device is also available in gold, or as a globe-shaped keychain. Each arrives with software, instructions and a wallet ID card directing medical staff to the locket (or keychain). Hey, it's never too late to buy a Valentine's Day gift for you or your love.
