It may be ages before Apple finally adds NFC to the iPhone, but don’t let that close any doors on you and get a CalypsoKey instead. This dual-antenna (13.56 MHz and 125kHz) transmitter sports 1k of memory capacity and opens NFC-compatible locks with just a tap of an upgraded CalypsoRing, CalypsoLoop or CalypsoCabrio case, letting you ditch stand-alone NFC keys for something a little more practical.

Learn more about their range of cases (with and without CalypsoKey) at CalypsoCrystal – roughly $160+
