Hybrid and ensemble neural network frameworks that combine temporal, relational, and anomaly-detection capabilities consistently achieve superior real-time fraud detection performance in credit card networks and instant payment systems.
As of its March 5 2026 publication, this narrative literature review surveyed how neural network architectures are used for real-time financial fraud detection, covering MLPs, LSTMs, CNNs, Autoencoders, GNNs and Transformers, and the production requirement to operate within sub-100-millisecond payment authorization pipelines, with examples from credit card networks and Brazil's PIX system.
