Hi , i have a POS system and i would like to use the EFT on it. I am very new to this environment and working on a POS system with other fellow developers some of them have left the company.
Can someone please shed a light to this whole EFT POS? We already have a third party that will handle the sending of Data to the Bank. Right now i'm stuck in a sense that i do not know how to send my transaction data from the POS to the Third party that will send to the Bank for verification. Please help me.
