How do debit card authorizations work

The actual funds transfer only happens after you submit a batch of transactions to your acquiring bank. Even if you submit batches regularly, it could still take several days for the funds to show up in your account.

That timing could create a problem. Without an authorization hold, a cardholder could theoretically make a purchase, then drive straight to an ATM and withdraw all the money in the account. If that happens, you get stiffed. It remains on hold until settlement or until the time limit runs out.

Lodging is a good example; hotel guests know the price of the room beforehand, but they may use room service during their stay. They could also check out early, or charge a bar tab to their room. As a result, hotels don't know exactly what a customer's final bill will be until after checkout. With a hold in place, customers can't spend your money—either accidentally or intentionally—before you settle the transaction. The funds are simply released from the hold if an order is canceled before settlement.

This saves you the time, hassle, and fees of processing a return. For merchants, authorization holds help minimize risk of offering delayed billing. Those are the direct benefits. If we take a broader view, though, we can see an authorization hold as a great way to help prevent chargebacks.

However, using a pre-auth gives you time to validate charges and look for potential fraud. The time limit for an authorization hold depends on different factors. Your merchant category code MCC , the card network, and the type of payment card used all play a role. Most debit card transactions have a hold time between one and eight business days. For credit card transactions, though, the hold might last as long as a month. The card networks understand that this can create problems for both merchants and cardholders.

And no wonder. But what really happens when a consumer makes a purchase with a debit card? The network ensures the pieces of transaction data are correctly formatted.

Then, it performs a fraud analysis and forwards the information to the bank that issued the debit card. The transmitted data typically include the card number, transaction amount and date.

If the consumer entered a personal identification number, or PIN, that would be encrypted and sent as well, Whyte says. At the end of the day or several times throughout the day, the merchant sends all the authorized transactions back to the network, which splits up and recompiles those transactions and then sends them back to the issuers. Finally, the network calculates how much money each issuer owes the network and how much money the network owes each merchant, Whyte says.

Payment of the funds to the merchant can happen the same day as the swipe, or the next day, or within a few days. The volume of transactions processed is staggering.

Whyte says the Visa network routed more than 7 billion U. The back of the card contains the magnetic strip, or stripe, a security code and signature panel, Kadletz says. Two examples: An authorization to purchase gasoline up to a certain dollar amount might be adjusted after the fuel is pumped into the tank, and an authorization to pay a certain dollar amount for a meal at a restaurant might be adjusted after the diner adds a tip to the total. Visa and MasterCard tend to process signature-based transactions, which typically use a so-called two-message process in which authorization and settlement are performed separately.
