Stand Alone Credit Card Terminals & It’s Communication

Many years ago before the internet, the old “ma bell” phones and the phone lines operated on sending/reading pulses.  With the advent of the internet a new system has come to the market called voice over internet or VOIP.  Today most if not all phone system uses VOIP or Digital Phone lines. If not in your office / business, but at the switching stations.

Today’s credit card terminal, when using a phone line and the built in modem, is based on the old “ma bell protocol. Voice over IP or Digital Phone lines simulate this pulse, which isn’t always sufficient for what the terminal is looking for. For this reason if a merchant has VOIP we recommend  processing over IP instead.  It must be a wired internet connection.  Wi-Fi will not work for the vast majority of stand-alone credit card terminals.
