Dear Br.

Opening a checking account that does not generate interest is permissible because you do not earn or give any interest. It has become a necessity in our times as you notice in your case. We all deal with conventional banks and we make our best to avoid interest.

 

However, if there is an Islamic bank in your area, it is much better to deal with it because even when you have only a checking account, the bank may use your money anyway.

 

Allah Almighty knows best.
