A bank account blending savings-account interest with limited checking features.
A money market account is a deposit account that typically pays interest comparable to a high-yield savings account while allowing a limited number of checks or debit transactions. It is FDIC-insured. Note it differs from a money market fund, which is an investment product and is not FDIC-insured.
A money market account can hold short-term cash you may need to access by check a few times a month.
