Walmart won't be denying check cards any time soon.
Take a look at your interchange fee schedule for this year, against year. For VISA, last year there were ony a few catagories. This year there is an entire page of them. Different rates for large and small companies, grocery stores, hotels, car rentals, small ticket, large ticket - you name it.
Stores with huge volume sales get the best rates (Guess who tops the list) with an overall drop of 25-30% or so from last year. You've propapbly already seen the drop in interchange income to your institution.
The bottom line is, everyone will probably still take check cards - you will just get a smaller piece of the interchange pie.
