CalypsoKey: Never Remember Where You Put Your Keys Again

This whole NFC (near field communication) thing is starting to catch fire, eh? The latest device to take advantage of the technology is the CalypsoKey,¬†which lets you totally forget your keys in your girlfriend’s purse, the empty seat next to you at the movies, or the supermarket produce aisle because you have this weird thing about scraping your house key against fresh cantaloupe when you see it. No apps and no charging needed; just press your iPhone up against the Calypso-paired lock and you’ll be waltzing right into your home sweet home.
