First of all dont mention luxchecker i tried like 15-16 cards all Decline even i test them on sites they have money all his site gives me Red,red,red,red,decline.
So anyone can recomend a good Balance checker (CC) or any card balance checker.

try2check bro https://txgate.io/images/smilies/wink.gif pick right state, if you want valid just do under $1, checking balance be careful, it might be one hit and then dead

does it work for dumps too?

dont know i dont use dumps

yes you can put track 1 or two

Do not try check your normal CVV , unless it is fullz cc so you can check via PHONE , if you check balance on online chekers it usualy gonna kill your card / blacklist it..
