We will be implementing a key chain-type "port" for backers that request it! Questionnaires to all Kickstarter backers who may be interested in this feature will be sent in the days to come. As we would truly prefer not to see our little babies scratched over time by being in contact with keys! Don't worry! A small carrying pouch is being designed that can be worn around the neck, carry a key ring, as well as be slipped onto a belt is being developed! We will be offering this unit as an accessory for anyone interested!
