Historical Context
The concept of the Primary Account Number (PAN) was introduced alongside the development of credit cards in the 1950s. As electronic banking and digital payment methods evolved, the PAN became an essential element in securely identifying and processing financial transactions.
Structure and Components
The PAN is typically a 16-digit number found on credit cards. It is structured as follows:
- Issuer Identification Number (IIN): The first six digits that identify the institution that issued the card.
- Individual Account Identifier: The subsequent digits that uniquely identify the account holder.
- Check Digit: The last digit, which is used for validating the entire number using the Luhn algorithm.
Key Events
- 1950s: Introduction of the first credit cards.
- 1974: Adoption of the ISO/IEC 7812 standard for numbering systems in financial transactions, standardizing the PAN structure.
Detailed Explanation
Mathematical Models/Validation
The Luhn algorithm is used to validate the PAN. The algorithm ensures that the number is correctly formatted and has not been inputted incorrectly.
