How to Use Visatk
Visatk brings together 30 free tools for card payments, IP data and banking codes. This guide explains what each group does and how to read the results safely.
Quick start: your first BIN lookup
- Open the BIN checker from the Tools menu or the home page.
- Type the first six to eight digits of the card number. Do not enter the full number.
- Press the lookup button to see brand, type, level, issuing bank and country.
- Compare the country with the customer's IP or billing address if you are reviewing an order.
Tool groups
BIN & Card Tools
Look up card BINs individually or in bulk, compare a BIN with an IP address, and validate or generate test card numbers for development.
Payments & Risk
Understand payment codes: chargeback reasons, merchant category codes, AVS and CVV responses, and a checklist for investigating suspicious transactions.
Calculators
Estimate processing fees, foreign transaction fees and surcharges, convert currencies and calculate Luhn check digits.
IP & Network
Locate IP addresses, detect VPNs and proxies, look up many IPs at once, geocode places and test your connection speed.
Banking & Codes
Validate and generate IBANs, search SWIFT/BIC codes and find country calling and ISO codes.
Developer & Test Tools
Simulate payments with published test cards, generate test addresses, create and verify 2FA codes, test regular expressions, encode HTML entities and watermark images.
Reading results safely
- A BIN result describes the card range, not the person holding the card.
- A country mismatch between BIN and IP is a reason to review, not proof of fraud.
- IP city locations are approximate; rely on country-level data for decisions.
- A valid Luhn check only means the number is well formed, not that the account exists.
- Generated card numbers and IBANs are for testing only and cannot be used for payments.
- Fee calculator results are estimates; your provider's statement is the final word.
