CalypsoKey

Of all the features your iPhone 5 offers, there's one it doesn't: NFC compatibility. Fix this oversight by protecting it in a CalypsoCase with CalypsoKey ($120-$130). This add-on for the stylish CalypsoCase Loop and CalypsoCase Ring adds a dual-band RFID antenna with 1k memory to the luxury leather cases, letting you keep all your RFID-enabled identification cards with you, virtually, without having to load up your wallet.
