Buying Card Checking Method

[screamix]

I have merchant id numbers already for chase paymentech and one other service I won't name publicly. This does work 100% but I need to check like a hundred cards sometimes, and this takes a LONG time.
I need a way to check them at a faster pace than phone authorization. If anyone knows a FASTER way that works and won't kill or flag the cards, I'll trade for a merchant ID that you can use to authorize by phone.
