A check drawn by a credit union on its account at a federally insured bank would be an example of a cashier check. It is a type of check that is being issued by the bank being withdrawn from the own funds of the bank and being signed by the cashier of the bank. These are classified as guaranteed as funds since it is the bank that is held responsible for the payment of the amount. These are usually used in real estate and transactions pertaining to brokerage. This type of check has the name of the bank that issued it in an obvious location and it has improved security features like color shifting ink, security thread and watermarks.
