My square terminal is used in a coffee fund situation at work. The terminal is unmanned and only used by customers. We work off the honor system here so I have a sigh taped to the top of terminal that reads...
"Please make sure it says approved before walking away"
Everything works smoothly the majority of the time, but occasionally someone misses the onscreen decline notice.
It would be very helpful to have an audio sound when a transaction is declined to notify the customer.
Just make it optional in setup On/Off for people that don't want it.
Thanks
