FakecreditcardAbout BIN 557344
BIN 557344 is listed as a Mastercard Business debit card issued by Paywiser Doo in Slovenia. Debit cards draw money directly from the cardholder's bank account, so checkouts and gateways often treat them differently from credit cards (fees, holds, recurring billing). Business, corporate and commercial products are issued to companies for company spending and often carry different interchange fees from consumer cards.
Paywiser Doo has fewer than ten BINs in our data, so it has no bank page.
Slovenia has 261 BINs in the dataset; among the 189 that name an issuer, the main networks are Mastercard (48%), Visa (33%), Maestro (11%), and 49% are debit. See the Slovenia BIN list.

How many digits does a card with BIN 557344 have?
Mastercard card numbers have 16 digits, and the security code is a 3-digit CVC2 on the back. The first six digits are the BIN, the last digit is the Luhn check digit, and the digits in between identify the account.
Can I generate test card numbers with BIN 557344?
Yes. Open the generator with this BIN to create Luhn-valid numbers with expiry dates and CVVs for testing forms, validation and BIN-based rules. They are test data: not issued by Paywiser Doo, linked to no account and declined by real payment systems.
Does a BIN tell me whether a card is valid?
No. A BIN describes a range of card numbers — network, issuer, country and product — not a particular card. Whether a card exists or can be charged is known only to the issuing bank. To check the format of a full number (length and check digit), use the card validator.
A BIN identifies the card network and the issuing institution only. It reveals nothing about an individual card, cardholder or account, and it cannot show whether a card exists or can be charged. Test numbers generated from a BIN are for development and QA only and are declined by every real payment system.
