Security and privacy when paying at Casinos Con Bizum

Bizum Security Technologies

• Encryption (TLS in transit) — Bizum traffic runs through the bank infrastructure and is protected with HTTPS/TLS so payment data is encrypted while it moves between the app, bank systems, and payment rails.
• Bank-grade data handling — Bizum does not work as a standalone wallet; it is tied to a customer’s bank account and operates under the bank’s security controls for storage, logging, and access to sensitive data.
• Strong Customer Authentication (2FA under PSD2) — payments and key actions are authorised inside the user’s banking app with two factors (for example, something the user has: the registered device, plus something the user knows or is: PIN/biometric), as required by EU PSD2 rules.
• Device binding — the phone number is linked to a specific bank account and the banking app session is tied to the user’s device, which reduces the value of intercepted credentials on their own.
• Transaction monitoring and fraud rules — banks apply real-time checks to Bizum transfers, including velocity limits, unusual amount patterns, new recipient behaviour, and abnormal login or device signals; suspicious operations can be blocked or stepped up for extra verification.
• Limits to reduce loss size — Bizum applies operational limits (such as caps on transfer amounts and frequency) set by the scheme and enforced by participating banks, which contain exposure when an account is compromised.
• Chargeback-style protection is not built in for person-to-person transfers — P2P Bizum transfers are bank transfers: once authorised, they are typically not reversible, so the system focuses on preventing unauthorised access rather than “buyer protection” after the fact.
• Buyer protection depends on the channel — when Bizum is used to pay a merchant (Bizum for e-commerce), dispute handling follows the merchant’s refund policy and the user’s bank complaint process; it is not the same as card chargebacks and is not guaranteed for every case.
