While contactless payments themselves do not require complex mathematical formulas, the underlying encryption and tokenization technologies employ advanced algorithms like:
- AES (Advanced Encryption Standard): A symmetric encryption algorithm widely used across various industries.
- RSA (Rivest–Shamir–Adleman): An asymmetric cryptographic algorithm essential for secure data transmission.
- NFC (Near Field Communication): Short-range communication technology enabling data exchange between devices.
- RFID (Radio-Frequency Identification): Uses electromagnetic fields to automatically identify and track tags attached to objects.
- Tokenization: Replaces sensitive data with unique identification symbols.
