One major feature missing from Apple's iPhone, that's commonplace on many high-end Android devices, is near field communication (NFC). This allows NFC-capable devices to interact with one another, to make no-contact payments at businesses, or even to lock and unlock NFC-enabled door locks. Calypso Crystal is hoping to rectify the situation with its new CalypsoKey.
