  • Retail Banking Payments Standards Introduction Standards in Retail
    Central Bank of Egypt – Retail Payments Standards Retail Banking Payments Standards Introduction Standards in retail payments are vital for ensuring consistency across all domestic payments systems and compatibility with international norms. The primary basis for standards will be those defined by the International Organization for Standardization (ISO) for the financial services sector. The ISO standards defined by Technical Committee TC68 are specific to financial services and deal more with applications than technical specifications. Over the years ISO has delegated responsibility to different standards committees that act in specialized areas to augment the capacity of the ISO. The Joint Technical Committee (JTC) is one such committee that has been given responsibility for cards. They work in conjunction with the International Electrotechnical Commission (IEC) to develop the card standards. They develop standards for all cards including those used in the financial industry and others such as health care, transportation and others. In addition, other standards have developed around security. Important standards for security as regards payment cards are set by the Payment Card Industry (PCI) Security Standards Council (SSC). These standards aim to reduce the potential for card fraud, hacking and various other security vulnerabilities and threats. Compliance with the aforementioned standards will help to build the basis for interoperability across systems in Egypt. This is a key goal of this process. Each of the recommended standards will be briefly defined below. It is recommended that compliance with these be discussed and communicated to all stakeholders in the Egyptian payments community. Standards related to the financial services industry are evolving all the time.
