Monzo, NatWest and Santander are collaborating with Mastercard to develop and deploy the service across UK Faster Payments, for later in 2025
To support banks and deliver the payment protection consumers expect, Mastercard unveils Mastercard A2A Protect, a new global service launching first in the UK. „By combining cutting-edge fraud prevention technology and a new clear dispute resolution framework, Mastercard A2A Protect will enable banks to provide consumers with the appropriate levels of protection against fraudsters.” – according to the press release.
Today, 15 banks representing 90% of UK account-to-account payments protect their customers with Mastercard’s innovative AI powered real-time transaction scoring service Consumer Fraud Risk (CFR). Since its introduction in 2023, CFR has played a key role in reducing the number of APP fraud cases in 2024 by 20%1. Monzo, NatWest and Santander are working with Mastercard to build on that foundation to strengthen consumer trust when using Faster Payments.
„Mastercard A2A Protect will initially focus on the most acute needs, such as Authorised Push Payment fraud, providing a combination of preventative measures, consumer protections and a process to recover funds. Subsequent phases will establish a process for recovering funds across a broader range of scenarios, including where goods and services have been paid for.” – Mastercard explained.
Ultimately, the service intends to support participating bank customers before, during, and after each transaction, by:
Preventing fraud
1. Enhancing CFR’s transaction scoring capabilities and helping to identify more high-risk transactions, complementing banks’ own efforts
2. Leveraging Trace, a Mastercard solution which harnesses AI and network data insights to prevent money laundering and financial crime, and supports banks to identify and close ‘mule’ accounts
3. Delivering an industry-wide standardised fraud and loss reporting mechanism, which will provide banks with richer fraud insights
Protecting consumers
4. Providing banks with a simple framework and comprehensive set of multilateral standards to drive best practice and safeguard consumers. Efficiently addressing transactional and fraud protection issues, as well as goods and services protection issues, where relevant for consumers
Recovery of funds
5. Introducing a uniform procedure for banks to resolve disputes and recover funds, across multiple use cases via Mastercard’s existing centralised platform, reducing costs and speeding up resolution
“With Fast A2A comes fast fraud, and we owe it to consumers to have their back. Mastercard A2A Protect delivers meaningful benefits to every participant in a transaction.” Said Jorn Lambert, Chief Product Officer at Mastercard. „It lowers operational costs for financial institutions through standardised real-time fraud insights and streamlined dispute resolution, and all participants benefit from quicker and more predictable outcomes. Most importantly, consumers can feel reassured they have the appropriate protection when making account-to-account payments.”
Why This Matters
In the UK last year, according to UK Finance1, £592 million was lost to Account-to-Account fraud. The Payment Systems Regulator’s (PSR) has also taken steps to address the concern, introducing a 50:50 liability model for APP fraud. Mastercard A2A Protect adds to that with consistent expectations for consumer protections.
National Payments Vision
Through the National Payments Vision, the UK government is setting out the next phases of modernisation of account-to-account payments in the UK. A2A Protect is part of Mastercard’s approach to ensuring the UK’s Faster Payments ecosystem is ready for the future and provides people choice in how they pay and get paid while maintaining trust.
As a global solution Mastercard A2A Protect is designed to act as an overlay to existing account-to-account transactions, which means it can be applied to any A2A payment regardless of the payment initiation mechanism.
