The overview
Bizum is a local mobile payment system prevalent in the Spanish market, operating as an account-to-account (A2A) transfer mechanism supported by the majority of Spanish banking institutions.
It functions by linking a user's mobile telephone number directly to their bank account, facilitating real-time transfers without the requirement for sixteen-digit card numbers or IBAN entry at the point of sale.
For merchants, Bizum sits within the checkout as an alternative payment method (APM) that bridges the gap between traditional bank transfers and digital wallets. The system utilizes the SEPA Instant Credit Transfer framework, ensuring that the movement of funds is confirmed almost immediately.
By integrating Bizum, businesses can address the preferences of over 25 million active users in Spain who frequently use the service for peer-to-peer transfers and retail transactions.
This payment method helps reduce reliance on traditional card networks and is governed by strict PSD2 and SCA requirements through the participant's banking application.
How it works
Selection at Checkout
The customer selects Bizum as their preferred payment method on the merchant's checkout page. They are prompted to enter the mobile phone number associated with their Bizum-enabled bank account.
This action triggers a request through the payment gateway to the Bizum switch, which identifies the corresponding issuing bank for the transaction.
Customer Authentication
The user receives a push notification from their banking application or is redirected to their bank's secure environment. The customer must then authorise the transaction using biometric data or a secure PIN.
This process satisfies Strong Customer Authentication (SCA) requirements under PSD2, as the authentication is handled directly by the issuer.
Real-time Authorisation
Once the customer approves the payment, the bank validates the availability of funds. An immediate authorisation response is sent via the Bizum network to the acquirer or PSP.
This ensures that the merchant receives a definitive confirmation of the transaction status within seconds, allowing for immediate order processing.
Settlement and Reconciliation
The funds are transferred from the customer's bank account to the merchant's account, typically using the SEPA Instant infrastructure. Reconciliation is simplified as each transaction is associated with a unique reference number.
Merchants receive the proceeds according to their agreed settlement cycle, often faster than standard card-based clearing.
Why it matters
Conversion in the Spanish Market
Bizum has achieved significant penetration in Spain, with a high percentage of the adult population using the service regularly. Offering this method can lead to higher conversion rates among Spanish consumers who may be hesitant to share card details online but trust their banking application.
The friction of manual data entry is removed, which typically reduces abandonment at the final payment stage.
Reduced Dispute Liability
Transactions executed via Bizum are inherently authenticated via the customer's bank, which strictly follows SCA protocols. This reduces the risk of fraudulent 'unauthorised' claims compared to standard card transactions.
While refund processes exist, the credit transfer nature of the system provides merchants with a more stable payment environment and fewer retrieval requests related to cardboard fraud.
Lower Operational Overheads
As an account-to-account payment method, Bizum often carries a different fee structure than international credit card schemes. By bypassing certain interchange and scheme-fee layers, merchants may observe a reduction in the total cost of acceptance for Spanish domestic transactions.
Furthermore, the instant nature of the confirmation allows for more efficient inventory management and faster shipping workflows.
Use cases
E-commerce Retailers
Online stores targeting Spanish consumers can utilise Bizum to provide a familiar checkout experience. This is effective for fast-moving consumer goods where a quick, mobile-optimised payment process is essential for maintaining high sales volumes.
Subscription Services
Digital service providers can use Bizum for initial payments, though it is primarily designed for one-off transactions. It serves as an effective entry point for Spanish users to trial services before establishing recurring payment instructions.
Travel and Hospitality
Airlines and hotel groups can accept high-value bookings through Bizum. The instant authorisation and bank-level security help in securing reservations immediately without the typical delays associated with standard bank wire transfers.
Digital Marketplaces
Marketplaces operating in Spain can use Bizum to facilitate instant payments between buyers and the platform. This helps in building trust within the ecosystem by using a domestic payment standard recognised for its security.

This represents a significant majority of the Spanish adult population, reflecting an industry-wide trend toward domestic mobile payment adoption.

Questions about Bizum payments
What is the primary difference between Bizum and a standard credit card transaction?
Bizum is an account-to-account (A2A) payment method that initiates a transfer directly from the payer's bank account to the merchant's account.
Unlike credit cards, which rely on a line of credit and the Visa or Mastercard networks, Bizum utilizes the SEPA Instant framework and the customer's mobile number as a proxy identifier.
This removes the need for card number entry and often results in faster settlement and lower dispute rates because the transaction is authenticated directly by the issuing bank.
How does Bizum handle Strong Customer Authentication (SCA) requirements?
Biz_um is inherently designed to meet SCA requirements under PSD2. When a customer initiates a payment, they must confirm the transaction within their own bank's mobile application.
This typically involves two factors of authentication, such as something the user possesses (the mobile device) and something they are (biometrics like a fingerprint) or something they know (a secure PIN).
Because the bank manages this process, the merchant is granted a high level of security and protection against fraud.
Can merchants process refunds for Bizum transactions?
Yes, merchants can process refunds for transactions made via Bizum. The process generally mirrors the card refund workflow within the payment gateway's dashboard or via API.
Once initiated, the funds are transferred back to the customer's linked bank account. It is important to note that while the original payment is nearly instantaneous, the visibility of the refund in the customer's account depends on the processing times of the involved banking institutions.
Is Bizum available for international customers outside of Spain?
Currently, Bizum is primarily available to customers who hold an account with a participating Spanish financial institution. While the service is expanding its reach, it remains a domestic payment method for the Spanish market.
Merchants globally can accept Bizum payments, but the end-user must have a Spanish phone number and a bank account with a bank that is part of the Bizum network.
What are the typical transaction limits for Bizum payments?
Transaction limits for Bizum are determined by the individual's bank and the Bizum network regulations. For e-commerce, these limits are often higher than peer-to-peer transfers but still have daily and monthly caps.
Merchants should be aware that high-ticket items may occasionally be declined if they exceed a user's specific limit, though the method is widely used for a broad range of retail price points.
Does a merchant need a Spanish bank account to accept Bizum?
No, a merchant does not necessarily need a Spanish bank account to accept Bizum if they are using a Payment Service Provider (PSP) or acquirer that supports the method.
The PSP will collect the funds and settle them into the merchant's designated account, regardless of the bank's location, although foreign exchange fees may apply if the settlement currency differs from the transaction currency (EUR).
How does Bizum impact the merchant's chargeback ratio?
Bizum typically has a lower chargeback ratio than card payments because every transaction is authenticated by the bank in real-time.
There is no concept of a 'friendly fraud' card chargeback in the traditional sense; however, customers can still raise disputes through their bank for non-receipt of goods or services.
These are handled through a retrieval and dispute process similar to bank transfers rather than the card scheme chargeback cycle.
