Checks are an important way to complete various banking transactions. Every check book has a finite number of checks that will need to be replenished. Checks can be ordered via online banking, third-party websites and directly through banks. There are many checks that a customer can choose from based on their banking needs. Personalization of checks and check books The checks can be customized to fit the customers requirements and this includes the font, color and also the design on the check. This level of personalization allows the customer to easily identify their checks and also to prevent fraud. The customer is also able to have their preferred aesthetic choice and this makes the checks unique. Single checks and duplicate checks In the case of single checks, the check book is smaller, and in case of duplicate checks the check book is bigger. The single checks contain checks that do not have a carbon paper underneath them. Hence, they cannot be recorded. Duplicate checks contain a carbon paper under every check leaf so that they can record every transaction of the bank account holder. These checks can be reordered in the similar means as single checks, but since they have more pages they are more expensive.
