Set Change without Purchase

The "Set Change Without Purchase" option lets operators configure whether the machine will allow customers to receive change from the inserted currency without making a purchase.

Note

When enabled, a customer can get change back after inserting a bill or coin; if canceled later, s/he can still get the money back. If the bill acceptor has no ability to giving change, equal value coins will be returned.

When disabled, once customer inserts cash, s/he can only use the money to buy at least one product.
