Read full description

Fidel's primary clients are businesses that want to leverage real-time payment events to create more relevant and powerful user experiences. These businesses can include a wide range of industries, from retail to hospitality to e-commerce.

Fidel also places a strong emphasis on security and privacy. They use card number tokenization, a process that replaces sensitive card information with unique identification symbols, to ensure user privacy and prevent sensitive information from being leaked.

In addition, Fidel provides a range of tools and features to help businesses get the most out of their services. These include a management dashboard, webhooks, detailed documentation, a test environment, versioned API changes, metadata support, and a sample app.

In summary, Fidel is a fintech company that provides businesses with a secure and reliable platform to connect to their users' cards, capture purchases in real time, and create more relevant user experiences.
