Terminals
We support a variety of terminals for credit card processing, debit, PIN debit, gift, and EBT processing as well as tip adjustment.

Mercury-enabled credit card terminals are not connected to the POS or ECR. Instead, they send transactions directly to us. Our terminal support team makes sure merchants get exceptional customer and technical support, 24/7. Our terminal processing solutions have pre-loaded software for quick setup and can accommodate high-speed internet (IP) or dial-up processing.
