Which stores are not affiliated with certegy?

I believe that Winn-Dixie, Publix and Walmart use telecheck. I know that K-Mart and Walgreens uses certegy. I had a negative experience with Certegy yesterday; however, I called customer-service and they say the problem was remedied and I should be able to write checks today. I will try K-Mart again and see if they corrected the information in their file.
