You don't need to activate your Mighty Card or worry about a battery expiring, the Mighty Card runs automatically without a battery when exposed to an RFID field.
To operate your Mighty Card simply place it with your other RFID enable cards preferably together on one side of your wallet or purse. Card outside of 1 inch radius are not optimally protected. Be sure that the cards also align and overlap by at least one inch but the more coverage area the better.
