End-to-End (E2E) encryption, security keys, and tokenisation are core but distinct technologies in safeguarding payment data. E2E encryption ensures data remains unreadable from sender to recipient. Security keys control system access, while tokenisation replaces sensitive information (e.g., card numbers) with non-sensitive tokens to prevent misuse.
