#8 - I do like the emphasis on "Impact," with the Payment Systems less stressed and small below. I also like that the font used is modern, but not too creative. This logo needs to be simple (but modern) and convey professionalism and security. I like the idea behind the lock mark, but it is not exactly the right look... also the "i" looks like a "j."
#11, 14 - I like the font and weight of these two the best. (I do prefer straight lines to curves.) I like the idea of the mark, but am not totally there yet.
