Well, my card doesn't need a battery but works just like mobile payments (take out, press against reader, done) whereas google maps has many advantages over a paper map (i can find exactly where I am, search for things & get traffic updates).

Phone payment app can also feature improvements over a card, like knowing and showing your balance, helping you track spending, prompting you to use discount coupons... whatever the provider can come up with.
