Have to agree 100% with this. I mean how many loyalty cards are you supposed to carry around with you? Homebase, Tesco, Sainsbury & Boots are all places I frequent. I give my wife the Boots receipts and she adds them to her account when she remembers. I've lost my nectar card. My Homebase card has an uncanny ability to disappear and reappear at will and Tesco is the only one i'm consistent with, usually because I use the credit card rather than the classic club card.

How about creating a multi-loyalty card that allows you to accrue through several stores with a single piece of plastic???
