yes you will get credit cards points, just by swiping and change back, tomorrow bank in again. but you have to pay 2% i think for every cash out transactions

2% is levied by all cards for any cash withdrawals, if non cash, normally the seller absorb thru the goods sold. that is why if the profit is too low like selling camera , video player they normally ask for cash from you.  no loop hole lah  credit card company so stupid?  they are worse then loan shark.  believe me
