How Does a Credit Card Transaction Work?
The process of each transaction takes just seconds, but there is so much that goes into it. And though the cost is frustrating sometimes, when you think about everything that goes into making it happen it becomes a bit more understandable. That’s not to say that many merchants aren’t being overcharged!

When a customer makes a payment, whether they dip, swipe, tap, or key in, the information is immediately sent from the payment terminal to several different parties.
First it goes through the payment processor to ensure that the transaction is valid and follows all PCI compliance rules.
At the same time, it also travels to the appropriate card network – Visa, MasterCard, Discover, etc. These agencies are responsible for setting the interchange rates (variable fees based on the inherent risk of any transaction). This assigned fee, typically constituting the bulk of a credit card processing fee, will be attached to the final processing total after sales are batched.
Lastly, the card information will be sent to the issuing bank (the customer’s bank) to check for sufficient funds and any fraudulent activity.
The issuing bank then sends the official response back to the merchant’s terminal where the card will get an approved or declined response.
If approved, the transaction will be queued for batch processing at the end of the business day. The funds will be released from the issuing bank and deposited to the acquiring bank (the merchant’s bank) with all processing charges deducted from the total. These are usually completed within 24 hours of the transaction.
So What Happens to Credit Card Processing When the Internet Is Down?
All of the technology that got us to where we are today is erased once the internet is down. Without the internet there is simply no communication between the credit card terminal and the card networks, processor, or banks.
And depending on your city, downed internet can be a daily occurrence. A lot of major cities have constant repairs or bottlenecks that inhibit credit card sales. So it’s important to be prepared.
This doesn’t mean, however, that your business is temporarily shut down. There are some easy ways to work around the issue until your internet connection is back up and running.
What’s the Difference between Online and Offline Mode?
While a hiccup in internet service is never ideal, it doesn’t mean that your business is helpless. With the right retail point of sale and peripherals, you’re nearly able to operate as normal.
Beware of offers, though, that say that credit cards can be processed offline. Being offline means that you have no internet connection and therefore no communication through your WiFi.
During normal online times, your business can operate as normal with a full connection to your wifi. All transactions are processed through the card terminal and sent to each respective party through the WiFi.
How Can Business Run on Offline Mode?
Now, as we said, being offline doesn’t mean that you can operate your business exactly as you normally would. But below are some ways that you can get quite close to doing so.
Use Store & Forward
Most modern cloud-based POS systems can store card information even when offline. This does NOT mean that the transaction will be processed in real-time. Instead, it’s simply stored and then processed as soon as the POS comes back online.
Add a Phone Backup
Most credit card terminals also have a port for adding a phone extension. This wired version means that your store will only be set back technologically 25 years instead of 50. All transactions can be processed in real-time, but you’ll be going back to a dial up connection and each sale may take a few minutes. Still, it’s better than nothing.
Get a Second Internet Line and Load Balancer
These days, it’s surprisingly easy and affordable to add a second internet line. Retailers can typically do so for under $50/month. This allows your terminal to connect to the other network automatically anytime one is offline.
Additionally, a load balancer helps distribute any traffic going through your networks. This increases the overall speed and ensures you have the fastest transaction time possible.
Set Limits to Offline Mode
While store & forward is a great tool to have, it does increase the chance of fraudulent transactions. If a card is declined or cancelled, there is virtually no way of retrieving compensation from the customer after the fact.
Therefore, it’s important to set limits on the value of all store & forward transactions. Automatically set these in your POS system to avoid costly losses.
Use Voice Authorization
One common work around for the larger transactions during offline times is to use voice authorization over the phone. It’s time consuming and will hold up your checkout line, but it does ensure that a particular transaction will go through. A merchant can call their credit card processor who will then manually run the transaction for an additional fee.
What Should Merchants Watch Out for With Offline Mode?
While the tips above make being offline a whole lot more bearable, there are still some issues to watch out for when offline.
- No transactions are authorized in real-time. All transactions are instead stored in the POS to be authorized once the internet is back up and running. This means that any declined cards will result in lost sales.
- If a sale is processed offline but disputed by the cardholder, the sale will almost always result in a chargeback, again leaving the merchant on the hook.
- Voice authorizations can be a huge pain and will come with premium surcharges.
- The back office features and analytics of your POS will not be available offline.
- If you don’t set specific limits on offline transactions, cashiers will be able to store & forward every transaction.
- During periods of longer internet outage, such as a natural disaster, speak with your credit card processor. Store & forward charges are not kept indefinitely.
