Is there a way to charge a customer based on how much they dispense after they swipe their card? Hoping to implement something similar to a gas station where it puts a hold on their card until they’re done.
Yes, you can set up a system that places an authorization hold on a customer’s card before dispensing, similar to gas stations. This is often achieved using a "pre-authorization" setup through your payment processor. Here's how it generally works:
Pre-Authorization Hold: When the customer swipes their card, a hold amount is placed to confirm funds. This hold typically covers a maximum estimated charge.
Metered Dispensing and Final Charge: As the customer dispenses, the system tracks the amount, and once finished, the hold is adjusted to the actual charge based on usage.
Releasing Excess Funds: After the final amount is charged, any extra hold amount is released, usually within a few days depending on the bank’s policies.
To implement this, you’ll need a POS system and payment gateway that supports pre-authorization and metered billing based on real-time usage. Discuss these options with your payment processor to ensure compatibility with your specific setup.
