Too many loyalty cards!

The companies are going crazy now to lock the consumers .They are trying to attract and involve with consumer by introducing club cards and etc. Where the consumer will purchase the product and use the cards offered by the stores.Its a good idea to cope up with consumers.But the thing is , there are so many cards that you are wallet or handbag ended up with full of loyalty cards.This is the problem , once someone start doing something unique other seems to followed. As a result , its uniqueness kinda dies.So why not company does something that doesn't involve carrying stuff.

A few weeks ago I went to boots , on the cash point the cashier asked me if i have a boots advantage card.There was a huge que behind , i was looking through my wallet , but it was so many cards including Nectar card, Tesco club card,Morrison match and more card, Holland and Barrett card , and also including my credit card and bank cards.I know i have some of the cards but people have so many cards for example , sainsbury rewards card, Costa coffee club ,My Waitrose card and so many.Anyway ,at the end I gave up to find my card.The que behind me seems to be irritated by me.I bet some other consumer feel the same way as I feel. Obviously . everyone like to be rewarded, gets discount and free products.And also if it is from your favourite store , then it boost up more.But it drive away consumer because its too much to carrying all the cards at the same time and also its irritating as well.So why not the companies try to make something that consumer doesn't have to carry all the cards but also they will get the rewards for purchasing the products.May be a code or number that will indicate individual consumer or the email address.I mean something that can help to connect but not to carry.
