HOW IT WORKS

START HERE
  1. Create an account and log in to your dashboard.
  2. Fund your balance with BTC or LTC — deposits are credited automatically, usually within minutes.
  3. Choose a checker, paste your list, and run the check.
  4. Results are shown instantly and stored in your history.

Your balance is only used when you run checks. Each checker shows its cost before you start, and there are no hidden fees.

CHECKER TYPES

4 TOOLS
root@node:~$ checkers --list
ALL COUNTRIES CHECKER

A non-charging, non-authorizing check that works for all countries. It is super fast and never kills the card — send as many checks as you need without affecting the card.

CHARGED CHECKER

Places a small real charge of $1–$5 on the card, which gives you a 100% confirmation that the card is live and chargeable. It is not as fast as the all-countries checker, but it is very, very accurate.

AVS CHECKER

Matches the billing address to the card, making sure the address on file is the correct one.

GENERATED CARDS CHECKER

Added due to high user demand. A super-fast checker, just like the all-countries checker, but this one also allows generated cards.
