Re: Loyalty cards - you can almost always just enter your phone number at merchants. I've encountered no exceptions to this, but I'm sure they exist.

That's why the majority of them stay at home. For some reason, the grocery stores, when doing self-checkout and such, don't have email input or phone number. :(

EDIT: I should add that the main grocery store I shop at, you scan your card when you enter and are given a wand to checkout your groceries as you add them to the bag.
