Which piece of information is typically not found on a personal bank account's signature card?

The typical contents of a personal bank account's signature card usually include essential identification details that help the bank verify the identity of the account holder. These details often consist of the account holder's name, a personal identification number (such as a social security number), a telephone number, and the address of the account holder, which are all relevant for establishing a clear identity and maintaining accurate records.

In contrast, while some financial institutions may collect a thumbprint for added security measures, it is not a standard practice found on all personal bank account signature cards. Thumbprints might be used in specific circumstances, such as for fraud prevention or in cases where an individual cannot provide a signature, but they are not a usual feature of personal bank account documentation. Therefore, the information item that is typically not included on a personal bank account's signature card is the thumbprint of the account holder. This distinction highlights the variation in procedures among financial institutions and their differing approaches to identity verification.
