How banks recognize casino payments

1. Introduction

The payment of casinos by credit card in Australia has become the object of strict regulation. Banks are required to monitor and block gambling-related transactions. Players are often surprised how exactly the bank "sees" that their payment refers to online gambling. In practice, this is achieved through a combination of transaction codes, analysis algorithms and anti-fraud systems.

2. Role of MCC codes

Merchant Category Code (MCC) - a four-digit code that is assigned to each outlet.
For gambling, MCC 7995 ("Betting, including Lottery, Casino Gaming Chips") is most often used.
If the bank sees that the payment goes to the merchant with MCC 7995, it is automatically classified as a casino payment.
In Australia, most licensed operators are required to transmit this particular code.

3. Using payment gateways

Online casinos often operate through international processing centers.
If a transaction passes through an offshore gateway, the MCC may masquerade as "entertainment services" or "e-commerce."
Banks apply additional filters to recognize such schemes.

4. Algorithms of anti-fraud systems

Banks use behavioral analysis:
  • unusual amounts (for example, frequent deposits of $50- $200);
  • regularity of transactions (game deposits often pass in series);
  • recipient geolocation (Curacao, Malta, Gibraltar, Philippines).
  • If a transaction falls under several triggers, it is blocked or sent for manual verification.

5. Impact of legislation

In 2023-2024, Australia introduced a complete ban on paying for online gambling with credit cards.
Banks are required to block transactions with MCC 7995 regardless of amount.
Even if the casino masks the code, the bank can use its own black merchant databases and block payments.

6. Exceptions and workarounds

Debit cards: often pass more successfully, as the regulation is softer.
E-wallets: allow you to hide the source, but they are also tracked.
Apple Pay/Google Pay: can temporarily bypass filters if the merchant passes another MCC.
Cryptocurrency gateways: Eliminate banking controls altogether, but carry additional risks.

7. Practical value for the player

When paying with a credit card, the probability of blocking the transaction is very high.
Even a past deposit can cause further withdrawal denials.
Banks monitor customers and, with regular "gaming transactions," can lower their credit rating or limit the card.

8. Conclusion

Australian banks recognize casino payments mainly through MCC codes and anti-fraud systems. Even attempts at camouflage with offshore gateways gradually stop working. Using credit cards for casino deposits is becoming increasingly risky and unpredictable, and players should consider both the legal and financial implications of such transactions.
