What option do I choose to withdraw money out of my card: checking, savings or credit?

You should choose credit when withdrawing money from your card.

You choose checking

I always choose checking.  You can try credit but I don't know, why you'd chose credit?  Sometimes at the store I have to select credit, sometimes debit and enter the 3 digit code on the back or 4 digit on the front.  Most times it just goes through without me choosing credit or debit.

At ATM MAchine you always Select Checking Account. Never Check Your Balance as its a trick ATM Vendors use to add a fee to Transaction and it also slows down the entire withdrawal process. Also, there is a $200 per transaction Max however you can do $200 $200 $200 $150 to Withdrawal the $750 Max Cap per account per Day ATM Withdrawal. ALL 7-elevens ATMS nationwide are FREE to use your Bluebird Card while Withdrawaling Funds! Cheers
