In short, KioskBuddy supports cash payments but does not support integration with any cash drawers. Cash payments are disabled by default.
KioskBuddy has an option to accept cash, but bear in mind that it is not the most ideal process, since the iPad can't collect cash. The way it works is, if cash is enabled, the customer will have the option to choose between card or cash. If the customer chooses cash, their order go through and will be tagged as a cash payment in the order name. Then some time later, when the order is ready, it’s up to your staff to trade product for payment.
Some trusting businesses operate based off of an honor system with a cash box left in public next to the kiosk, but proceed at your own risk!
