Credit Card Fraud Prevention Rules 

by Unionbank Human Resources Group

In 2025, UnionBank faced a surge in credit card fraud driven by increasingly  sophisticated social engineering tactics. Fraudsters exploited legitimate-looking SMS  sender IDs to trick clients into entering sensitive information on phishing sites, leading to unauthorized transactions. This posed a serious threat to client trust and operational  integrity. UnionBank needed to respond with a solution that was not only effective but  also aligned with its digital-first, innovation-driven culture, and aligned with Aboitiz’s  Great Transformation.  

Beni, a fraud strategy specialist, designed and deployed a set of authentication fraud  rules that proactively intercepted suspicious transactions before OTPs could even be  sent. By leveraging data analytics to identify recurring fraud patterns, she built a rules 

based filter that blocked fraudulent attempts at the earliest stage. Her approach  reflected the techglomerate mindset—using technology to drive smarter, faster, and  more adaptive solutions. She also continuously monitored dispute data to ensure the  Bank’s fraud prevention strategy evolved in step with emerging threats. 

Since June 2025, Beni’s solution has blocked 791 fraudulent attempts, preventing  potential losses of ₱81 million. The Bank also recorded a 60% reduction in OTP authenticated fraud losses, validating the effectiveness of her preventive strategy. This  not only strengthened UnionBank’s fraud protection framework but also demonstrated  how the Great Transformation’s emphasis on AI, data, and innovation can directly  enhance customer experience and operational resilience.
