The signature of a check is usually stamped with a hand stamp and a financial stamp. When withdrawing cash, the bank staff will ask the drawer to fill in the ID number and name on the back of the check.
No initial approver is required, so you can leave it blank. Payee and initial approval column can be filled in according to actual needs, drawer column is required, and seller (seal) column should be stamped with special invoice seal. In practical work, the drawer and the initial approver cannot be the same person, otherwise it will not play the role of audit and control.
