What is a signature card used for in banking?

A signature card is primarily used in banking to verify the identity of the account holder. When an individual opens a bank account, they are required to provide their signature on this card, which serves as a reference for the bank. The signature card is crucial for ensuring that all transactions made on the account are authorized by the account holder themselves. In situations like withdrawing cash, writing checks, or conducting other banking transactions, the bank compares the signature on the transaction with the one on the signature card to confirm the identity of the account holder. This process helps prevent fraud and unauthorized access to the account, thus protecting the client's funds and maintaining the integrity of the banking system.
