choose your card(s) which feel right for you !
cards will be shipped withing 3 business days
upon receiving, scratch the spot at the back of your cards to 'free' the PIN (-;
register through 
please note : there is no card-replacement !
so choose a place which makes most sense to you. given that the cards have the size of cards you using on a regular basis, your wallet is just a suggestion. no guaranty though that that can't get lost either (-; at least you would have the cards on you and the generated field around you most of the time***
Many blessings*** !
