The Permanent Account Number (PAN) is a crucial document for financial transactions in India. It is a unique 10-character alphanumeric identifier issued by the Income Tax Department of India. The Mod 10 algorithm, also known as the Luhn algorithm, is a simple checksum verification algorithm used to validate credit card numbers and IMEI phone identification numbers. It can also be used to validate primary account numbers. This algorithm helps to validate that a credit card number is in the correct range and format and to identify the card brand.

Mod 10 checks validate credit card numbers
Mod 10 checks, also known as the Luhn algorithm or Luhn formula, are used to validate credit card numbers. It is a simple check digit formula used to validate a variety of identification numbers. The algorithm is in the public domain and is widely used today.
The Luhn algorithm was created by IBM scientist Hans Peter Luhn. It is a simple checksum formula used to validate a variety of identification numbers, including credit card numbers, IMEI numbers, and government identification numbers. The formula is specified in ISO/IEC 7812-1 and is designed to protect against accidental errors, not malicious attacks.
The Mod 10 check takes the credit card number submitted by a customer and validates that the number is in the correct range and format to be a valid credit card number. It also identifies the brand associated with the credit card number. This check is typically implemented on the website page where the customer enters their credit card information and presses the buy button.
The Mod 10 check helps prevent basic forms of attempted fraud and saves processing time and costs for merchants by reducing the need for manual intervention and call-backs. It is one of the lowest-cost and easiest functionalities to implement on a website.
The algorithm operates by moving from right to left, doubling every second digit. If doubling a digit results in a value greater than 9, subtract 9 from it (or sum its digits). The final sum should be divisible by 10 for the credit card number to be valid.

It verifies the correct range and format
The Mod 10 algorithm, also known as the Luhn algorithm, is a check digit formula used to validate a variety of identification numbers. It verifies that a credit card number is in the correct range and format to be a valid credit card number.
The algorithm works by taking the credit card number the customer submitted and checking that it is in the correct format and range to be a valid credit card number. This is done by performing a series of calculations on the digits of the credit card number. The specific calculations involved in the Mod 10 check vary depending on the position of the digit in the number. For example, starting from the left, the digits in the odd-numbered positions are multiplied by 2, while the digits in the even-numbered positions are multiplied by 1. If the result of multiplying a single digit by 2 results in a two-digit number, the digits of the result are added together to produce a new single-digit result.
Additionally, the Mod 10 check also validates what card brand is associated with the credit card number. This is important because consumers may accidentally input the wrong information, such as mistaking a Visa card for an American Express. By implementing the Mod 10 check, merchants can save processing time and reduce the clogging up of the system due to incorrect information.
Overall, the Mod 10 algorithm plays a crucial role in ensuring the accuracy and integrity of credit card transactions by verifying that credit card numbers are in the correct range and format.

It identifies the card brand
The Mod 10 algorithm, also known as the Luhn algorithm, is a simple checksum formula used to validate a variety of identification numbers, including credit card numbers. It was created in the late 1960s by IBM scientist Hans Peter Luhn and is now in the public domain.
The Mod 10 algorithm identifies the card brand by checking that a credit card number is in the correct range and format to be a valid credit card number. It does this by checking the first digit of the credit card number, known as the Major Industry Identifier (MII), which designates the category of the entity that issued the card.
The first six digits of a credit card number are the Issuer Identification Number (IIN) or Bank Identification Number (BIN), which identifies the institution that issued the card. These six digits are followed by the account identification digits, which are used to identify the individual account associated with the payment card.
The Mod 10 algorithm can be used to validate credit card numbers by performing the following steps:
- Starting from the rightmost digit, double the value of every second digit.
- If doubling a digit results in a two-digit number, add the two digits of the number obtained after doubling to get a single-digit number.
- Get the sum of all the digits.
- If the total sum modulo 10 is equal to 0 (i.e., the total ends in zero), then the number is valid according to the Luhn formula; otherwise, it is not valid.
This algorithm is designed to protect against accidental errors and distinguish valid numbers from mistyped or otherwise incorrect numbers. It is important to note that the Mod 10 algorithm does not protect against malicious attacks or fraudulent activity.

It is a low-cost and easy implementation
The Mod 10 check is a low-cost and easy-to-implement method to validate credit card numbers. It is a simple checksum formula that verifies whether a credit card number is in the correct range and format and identifies the card brand.
The Mod 10 algorithm, also known as the Luhn algorithm, is a widely used, simple check digit formula. It is available in the public domain and can be used to validate a variety of identification numbers, including credit card numbers, IMEI numbers, and government identification numbers.
The implementation of the Mod 10 check on a website is straightforward and cost-effective. It is usually placed on the webpage where the customer enters their purchase information and credit card details. The code for the Mod 10 check is readily available online, with many development sites offering free snippets. As a client-side script, it automatically performs the validation when the customer submits their purchase information.
By implementing the Mod 10 check, merchants can save time and money in the order processing stage. It reduces the need for manual intervention and call-backs, especially during offline authorisation. Additionally, it helps prevent basic forms of attempted fraud by validating the credit card number format and range, ensuring that the customer has provided accurate information.

It saves time and money for merchants
The MOD 10 check is a low-cost and straightforward tool that can be easily implemented on a website. It validates that a credit card number is in the correct range and format to be a valid credit card number and confirms the card brand.
For merchants, implementing the MOD 10 check saves time and money in several ways. Firstly, it reduces the need for manual intervention and call-backs, especially for those doing offline authorisations. This saves time that would otherwise be spent going back and forth with the consumer during order processing. It also eliminates the cost of paying for each authorisation call.
Additionally, the MOD 10 check streamlines the order processing procedure by reducing errors in consumer-inputted information. Without the check, consumers may transpose numbers, omit digits, forget to input the expiration date, or provide incorrect card type information. These errors slow down order processing, clog up the system, and can lead to basic forms of attempted fraud.
Moreover, PAN verification is a valuable tool for merchants to safeguard their businesses from identity theft and fraud. It helps to ensure regulatory compliance and facilitates Know Your Customer (KYC) processes. By verifying the validity of PAN cards, merchants can confirm the identity of individuals or businesses in real time. This protects the business from financial losses and reputational damage caused by identity fraud.
Overall, the MOD 10 check and PAN verification processes offer significant benefits to merchants by streamlining operations, reducing costs, and enhancing security.
