For new companies, such as Adelo Software with a point-of-sale solution for the restaurant industry, the change will be less dramatic, said company president Harry Tu.

"When we developed our system we built our foundation for this kind of credit card security," Tu said, adding, using PPI there were only some minor gaps in their application.

However, Tu said, if an ISV has its software already out in the market it could become a big headache.

"Once the finalized code base is released to the public then they will have to do all of these changes, and the cost is very significant," Tu said.

In essence, the VISA PABP requirements will create a cascading effect that will impact all of the participants in the credit card payment food chain -- not just ISVs with a point of sale package.
