While these three terms may be used interchangeably, there is a difference between them. A time card is a ticket that employees have that tracks the amount of time worked. They insert the time card into a time clock, and the time clock stamps the card with the current time to note whether the employee is beginning work or “clocking out.” This process has been used historically prior to the invention of the technology we have today. Employees enter their time on a time sheet instead of using a time clock to stamp it. They can also enter the specific work they did during that time. A time sheet can be paper where the employee writes in the time or an app or software where they note the time digitally. Paper time sheets are harder to track and leave room for error, so most employers use digital tracking. The method for tracking employee time has advanced over the years. And although some employers may use time cards and a time clock, other employers use advanced technology like fingerprint and retinal scans for employees to clock in and out.
