The crossword solution for the term 'CHECK A CHECK' is READD, which stands for Remotely-Activated Electronic Deposit Device. This is a type of automated teller machine (ATM) that allows customers to deposit checks without having to visit a bank branch. The customer simply inserts the check into the machine, which then scans and verifies the check before depositing it into the customer's account.
