I'm not really sure how to explain it, other than it's a method of sending money to someone's bank account, from your own bank account. All that's required is each person setting up their own PayID within their own account, then the one who is to receive money just gives the sender their email address or phone number, depending on what they used to set up their PAYID. I think from memory, that's about all there is to it. Where it's located within one's account is where one would go to send money.
