Cash Back with credit cards

There are banks in UAE that are offering credit cards with cash back option. One such banks that i know is RBS.

RBS offers platinum cards and other credit cards of which weekend credit has 2 % cash back if purchases are made on weekends and 1 % cashback if purchases are made on other days. ofcourse there are other offers also with these like Wild wadi, ski dubai and movies.

One way to earn money would be to use these cards on weekends. But also check your statements regularly to see that the cashback is reflecting.
