I was a cashier. A lady forgot her credit card for there store so I did an account look up and printed the lady a temporary charge card. After the lady made her purchases, she left, and left her temporary charge card. I put a $20 gift card on the ladies card without her consent. The store found out and said they are incouraging her to prosecute. How much trouble can I get in and how do I go about taking care of this? Can I get the ladies contact info and just pay restitution? The gift card has not been used. Is the store I worked for even allowed to give me the ladies information so that I can make this right?

I live in Ohio by the way.
