Sometimes depends on the bank and sensitivity of the bin. Knowing the balance would be useless IF you are carding in store.
I have tested this with many hand skimmed local dumps where I got bank insiders to check the balance to produce better work. But do keep in mind balance is not everything, afresh dump could have a 50K limit, but can still decline on POS for a coffee purchase
To sum it up how well a dump may hit depends on:
- region lock
- bank security
- purchase sensitivity (types of purchase, ie. apple electronics kill cards FAST)
- original card holder's spending frequency and amount
- orginal card holder's location , time zone and spending habits (you could be buying an apple product in Canada while the owner is using for his DAILY coffee run in Africa)
Some of the above pointers applies on the heavier side on things when it comes to local hand skimmed dumps.
Hope this helps.:rocks
