What do Proof Operators do?

A check is a bit like an IOU. It contains information about who owes the money, whom that money is owed to, where the money should come from, and where the money should go. Computers called proofing machines stamp that information on the checks. As a Proof Operator, you run that machine and bundle checks for collection.

First, Proof Operators sort the checks into bundles by bank. You then take one check from one bundle and place it into the proofing machine. Proof Operators enter the amount written on the check into the machine, and then press a button. The amount that you typed is then stamped on the back of the check, and the check is canceled.

You do this over and over until you’ve gone through the entire bundle. The machine tallies the amount of money you’ve entered for that bundle, then you add up the checks by hand to make sure you’ve done your work accurately. After that, you tie the bundle together and send it to the other bank for processing.

In some banks, proofing machines contain scanners that read the amount of the check automatically. You’ll have much less typing to do if you use these machines, but you’ll be required to check the machine’s math, and you may find errors to correct from time to time.

Aside from number crunching, you perform maintenance tasks on your machine as well, changing its ink and tape frequently to make sure it’s ready for your workload. Since you don’t work directly with customers, you can dress casually, which means you’re not likely to get ink on your best suit.
