Question: how online checker works?

[Raymondicors]

anyone can give me details on how online dumps checker works.

if it was tested (checked) for 1$ for example to see if live ( approved) what happen?
it is tested on a pos? virtual pos?
the 1$ transaction will be shown on original card holder's transaction's card page?

can someone explain please?

Good question.

From what I understand, no, the transaction will be processed as pending and card holder will not see it. However, merches may be using the same servers to process the transaction, in this case you may end up with having multiple cards been checked from the same non-diversified source. Banks see that and react by banning the cards. To a very certain extent, it depends a lot on your luck.

Never heard of POS checkers

i want a checker to check at any amount even 100$

i want a checker to check at any amount even 100$

checking a card with $100 amount will certainly kill the card

Is using a checker just to see if the card is still valid or to see the amount available on it.. ?

The Checker works like this, User interface--> Merchant --> Back to user Interface. What that means that all these checkers are using merchants to do small transactions, they find a merchant that needs only front of the card and Expiry which can be found in the track. The on hold transactions are called a Pre-Authorization and no, the card holder can still see them in the online banking, once the money is returned the transaction goes away from online banking. Hope this helps, Cheers !!!
