Tokenization
Tokenization is the process of replacing sensitive data, such as credit card numbers or personal information, with unique identifiers called tokens. These tokens have no intrinsic value and cannot be used outside of their specific context, providing a layer of security for sensitive information.
Tokenization is commonly used in payment systems, where it helps protect cardholder data during transactions. When a user enters payment details, the system generates a token that represents the original data, which is then stored or transmitted securely. The actual sensitive data is stored in a separate, secure database called a token vault.
How CodeBranch applies Tokenization in real projects
The definition above gives you the concept — but knowing what Tokenization means is different from knowing when and how to apply it in a production system. At CodeBranch, we have spent 20+ years building custom software across healthcare, fintech, supply chain, proptech, audio, connected devices, and more. Every entry in this glossary reflects how our engineering, architecture, and QA teams actually use these concepts on client projects today.
Our work combines AI-powered agentic development, the Spec-Driven Development (SDD) framework, CI/CD pipelines with agent rules, and production-grade quality gates. Whether you are evaluating a technology for your product, trying to understand a vendor proposal, or simply learning, this glossary is written to give you practical, accurate context — not theoretical abstractions.
