Dear Guys at google answers:

Im a web programmer and web developer located in Central America. I
have created an online Mall. I will soon have hundreds of vendors
under the same domain. Now I want to provide them with credit card
acceptance services under my own logo. Something called "Private
Lable" service. (in other words, no other third parties involved in
processing a transaction like PayPal or others, just me and an
aquiring bank where I deposit the funds collected). This is achieved
buy buying what is called a payment server (software which is shipped
to you already installed in a CPU), or buying specialized software
which can verify whether a card is
valid and whether it has funds, which needs to be installed in my existing
web server. What I need from you is the largest list you can put
together of such software manufacturer. I only found www.credics.com.
Im sure there are many out there. Best of luck.. this is the first
time Im using your services and if it works I ll continue to use it
for many more searches I have in the pipeline.
