Summary
David L. Stearns studies how Visa developed from local bank card programs into a shared electronic payment network. The history covers both the technical systems and the agreements that allowed competing financial institutions to use them. Its chapters examine Dee Hock’s role in forming the organization, staffing and operating rules, authorization, clearing and settlement, standards, merchant terminals and debit cards. The account draws on documents and interviews to connect changes in technology with changes in relationships between participants. It treats a payment network as an organization as well as a computing system. The result is a detailed historical case of coordination, trust and the practical limits of shared infrastructure.
Why read it Our view
Use the chapters on operating rules, authorization and settlement to map the agreements behind a network product. Identify which parties must trust each other, which tasks need common standards and how technical choices change the power or duties of participants.
