What Is The PAI ISO Charge On Your Bank Statement?


Many people often get confused when they see the “PAI ISO” charge on their bank statements and want to know what it means.

“PAI ISO” stands for “Payment Alliance International Interchange Service Organisation,” or simply PAI ISO. To grasp the costs associated with debit and ATM card transactions, it’s important to understand this term.

It’s essential to know that the “PAI ISO” charge isn’t a rare thing – many bank customers experience it. Understanding that it’s a common issue is the first step in figuring out this financial puzzle.

Let’s explore the details of the often-seen PAI charge together.

What Is the PAI ISO Bank Charge?

The PAI ISO charge is a fee that banks charge for using debit or ATM cards. Banks and other financial institutions apply the PAI ISO charge which originates with the payment processor and is subsequently forwarded to the bank when processing debit or ATM card transactions.

The amount of the PAI ISO charge may differ based on the specific bank and the nature of the transaction, typically represented as a small percentage of the total transaction amount. Variations in charge amount contribute to the multifaceted landscape of this fee across different banking institutions and transaction types.

How Does the PAI ISO Charge Appear on a Statement?

A bank statement will show the PAI ISO charge as a cost related to ATM or debit card transactions. Payment Alliance International (PAI), the payment processor, charges the merchant a fee when you use your debit or ATM card to purchase. The PAI ISO charge results from transferring this fee to your bank or other financial institution. 

The PAI charge and transaction details are separate line items on your bank statement. The description of the charge may vary slightly depending on your bank but often includes terms like “PAI ISO,” “ISPA/PIMDS Withdrawal PAI ISO,” or simply “Payment Alliance International.” Examples of variations include “PAI ISO ATM Withdrawal,” “ATM Debit PAI ISO,” or other similar descriptions.

The charge amount represents the expenses for processing electronic payments, including maintenance, system upgrades, and payment processing company fees. It is subtracted from the total transaction amount. 

The expenses may accumulate even though they usually represent a small percentage of the purchase, mainly if you use your card frequently.
