What is "TFT" - Transaction Fee Transparency?

ONTOP Systems, through our Paylex Processing Platform, will be among the first to provide "near-real-time" merchant processing pricing data on credit card sales.


Our philosophy is that merchants can only comfortably grow their use of credit card payment technology when they are able to fully understand and optimize the costs involved.  We are pioneering this effort with our partners at TSys.  More soon!


Our goal is to help merchants by facilitating and streamlining payment processing activities, incorporating automation whenever possible.
