What's the difference between "Touch n Go" card and "Plus Miles" card? I believe the points obtained, rebate given and promotions are different.

I will keep my old Tesco Loyalty Card to score loyalty points. Then top up my Plusmiles card at places that accept Amex reload. In this way I get 7% cash back all year round, Plus points and rebates as well as keeping my Tesco points when I shop at Tesco and drive on Plus highways!
