Finally installing credit card acceptance in s.s. bays, and having trouble with some pricing aspects. For example, if I were to charge $4.00/4 minutes cash, can I charge $5.00/4 minutes credit card, which effectively changes the pulse rate per quarter thus charges more per minute for credit card. And if this scenario is not acceptable, can I do the same pricing with signage indicating cash price includes a cash discount. To the credit card sales would be added the sales tax as well. And apparently with Cryptopay the pulse rate/quarter must be the same in countdown mode but can be different in count-up mode. I am aware of the call/complaint issues with the count-up mode with failure to push the stop button. I am not sure if the advantage of count-up mode with the different price/quarter pricing allowance, and possibly more income, offsets the nuisance of calls from failure to use the stop button. The countdown seems quite simple by comparison. I welcome your ideas on this issue. Thank you.
