Frequently asked questions
What can I do with the Visatk tools?
Visatk offers free, browser-based tools for developers, QA engineers and merchants: look up card BINs, validate card numbers and IBANs, find SWIFT codes, calculate processing and FX fees, and geolocate IP addresses. They run format and mathematical checks only — no real card or account is contacted.
Are the generated card numbers or IBANs real?
No. Generated numbers are synthetic test data. They pass checksums so they look like real numbers, but they are not linked to any account and cannot be used for payments. They are for development, testing and learning only.
How do favorites work?
Tap the star on any tool to pin it to the top of this page. Favorites are saved only in your browser (local storage), so they stay private and are not tied to an account.
Are the Visatk tools free?
Yes. Every tool listed here is free to use in the browser with no sign-up. Membership plans only raise daily limits and add extras such as bulk export and an ad-free experience.
