Bizum payments 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 utilises 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 bizum payments 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 bizum payments 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.
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.
Bizum payments use cases
Mobile retail checkout
Spanish fashion and electronics retailers serving mobile shoppers risk abandonment when checkout requires card details instead of Bizum’s familiar phone number flow. Cardflo integrates Bizum through its payment orchestration layer, presents it for eligible Spanish transactions and returns the authorisation result to the merchant’s order management system.
Bizum for Spanish subscriptions
Retailers launching limited trainers, collectibles or cosmetics can face concentrated checkout traffic, while Bizum transaction limits may make the method unsuitable for some baskets. Cardflo helps merchants configure amount-based payment method display and route eligible Bizum requests through the appropriate acquirer partner integration.
Spanish event ticket sales
Spanish event organisers selling concert, festival and sports tickets need rapid payment confirmation before reserving scarce inventory or releasing a QR ticket. Cardflo connects the checkout to Bizum’s phone number authorisation flow and relays the confirmed payment status so fulfilment can proceed without manual reconciliation.
Bizum refund reconciliation
Merchants accepting Bizum must match completed payments and subsequent refunds against orders, particularly when finance teams reconcile busy daily sales files. Cardflo provides transaction references, payment statuses and reporting data from its acquirer partners, helping operations teams trace each Bizum payment through settlement and refund workflows.

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 utilises 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.
How does the Bizum phone number checkout flow work?
At checkout, the customer selects Bizum and enters the mobile number registered with a participating Spanish bank.
The payment request is then authorised through the customer’s banking environment, typically using the bank’s established authentication method, and the merchant receives the resulting transaction status through the integration.
Merchants should display a clear pending state until final confirmation arrives and avoid treating the initial payment request as completed.
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.

A merchant acquirer is a licensed bank that holds your account, takes liability for transactions, and settles funds. The payment processor is the technology layer routing data between the checkout, card networks, and issuing banks. Every card payment requires both components to manage technical encryption and financial liability. They are often separate entities with distinct fee structures.
