Okay... I still don't understand how this is better than simply putting the contact details on the card itself, other than the risk of staleness.

(And the marginal case where you want to revoke the ability to view your details after you give out the card, but before the person checks...hmm...)

This is better than business cards because you don't have to disclose any personal information like email, phone number and address. There's less pressure on both parties as well. I like Cheek'd, it's great for NYC.
