# Basis Theory

> Basis Theory provides APIs, SDKs, and tools for securely collecting, storing, and sharing sensitive data like card numbers, bank accounts, and personal information. It handles PCI compliance so you don't have to.

Basis Theory enables developers to accept payments, issue cards, run account updater, manage network tokens, and process sensitive data through a tokenization platform — without directly handling the raw data.
