actually it's simple.

Ur limit is 4k rite? but u want to use 6K? then u swipe twice 3k +3k = 6k

but of cos u have to bank in the remaining 2k in ur a/c first. Meaning u have extra 2k in your 4k cc limit rite?
meaning all in all u have 6k so just swipe 3k per tranx cos 4k limit meaning u can go max 4k per tranx but if
u have credit balance in your card then u swipe it also can get through as long it's not 5k per tranx.

That's what i did with all my cc

why 3k+3k and not 4k+2k since my credit limit is 4k?
the merchant machine is smart enough to accumulate both transactions together and consider it as a single transaction?

Oh it's just an example ma. If u want 4k + 2k also can one. As long not 5k as ur cc limit is 4k per tranx only ma
