From Consumerium development wiki R&D Wiki

    A wallet or purse is a worn device usually used to store identity cards, debit cards, credit cards, cash, coupons and condoms.

    Ideally, when the Consumerium buying signal says the product is good, you take money out of your wallet or purse and spend it. If not, the money goes back in, and you spend it on something else.

    It might be interesting if this also worked with people, and the use of condoms. This might make w:dating services one of the Consumerium Services.
