How to process cash back as service

[Anthill]

Hi, we have in our retail store some arcade games. Our customers not always have cash on them and want us to charge cash back on their card to use cash for arcades in store.

What would be best way to charge them as a service without us loosing money on fees plus reflect charge in and cash out in reports.

Thank you

Add a service fee for it like $1-2 on top of the amount of cash they want so that you don’t lose money on the processing
