Fund cards and authorize transactions in real time with Just-in-Time "JIT" Funding. Add your own rules, your own API decision engine, and your own data.
You approve or deny each transaction in real-time based on your business logic. You know your business best – if your incoming orders match the authorization request or if your borrowers qualify for another loan, you tell Marqeta to approve the transactions. If it doesn't look right to you, decline the transaction and mitigate risk to your business.
Each card maintains a $0 balance even as the card is being swiped. When the card is swiped, Marqeta asks you, the customer, if you want to fund the transaction. If you say it's authorized, Marqeta puts funding in the exact amount of the transaction on the card and then immediately deducts the funds from the card. This allows for greater control of risk and allows you to apply capital only when you need it. The end to end JIT Funding process takes an average of under 200 milliseconds.
