The best way to use Wave3 X cards is that they always carry with you and leave at different places, for example. When you drink coffee, leave a card, or even better, you can give the waiter a few cards, so for him to divide its customers ..
so that they give to your friends, to your family, and in a variety of restaurants, shops fast food, etc..
Wherever you go, leave a few cards, of course, ask the owner in each case will allow you to leave a few cards! :)
