Is it better to use checking or savings in PayPal?

What is the use of having a checking account if you already have a savings account?

• A checking account has a lower interest rate. Is the sole purpose of a checking account in this case is to allow a larger number of monthly transcations? But if you don't deposit all your cash to your savings account and leave some pocket-money instead, that defeats the purpose of a checking account, right? I just don't understand why someone should set a checking account if s/he has a savings account

• Answer:

  You would need a checking account if you need to issue checks. All businesses need checking accounts. If you're a student and pay everything by cash, then you might not need a checking account yet, but you will soon enough. If you're a company, you need to pay costs and expenses by check, e.g. rent, utilities, for purchases of inventory, etc.
