Security is essential for money transfer applications because they process sensitive financial information and transactions. PCI DSS applies to organisations that store, process, or transmit payment card data, or can otherwise affect the security of the cardholder data environment. Depending on the application, important safeguards may include encryption, secure authentication, access controls, transaction monitoring, vulnerability testing, and fraud detection.
