Step-by-step explanation:
The personal checking account that is the only exception to the daily transaction limit of purchase is a line of credit account.
A line of credit is a type of loan that allows you to borrow money up to a certain limit, and you can use it to make purchases just like a checking account.
However, it's important to note that using a line of credit will incur interest charges on the borrowed amount, so it's essential to repay the borrowed money as soon as possible to avoid high interest costs.
