The Flux card capture form is a hosted, shareable form that collects a customer's card and stores it tokenized in the vault without charging it. It is built for card-on-file workflows: authorizations before a job, setting up billing before service starts, or holding a card for incidentals and deposits.
Why businesses use it
Card on file, no charge
Collect and store a card now, then charge it when the work is done or billing starts.
Secure by design
The form runs on hosted fields, so the card is tokenized and never touches your systems.
No code needed
Share the form by link. There is nothing to build or embed unless you want to.
How it works
You share the capture form with your customer by link. They enter their card into PCI-compliant hosted fields, Flux tokenizes and stores it against their profile, and nothing is charged until you decide to charge it from the dashboard or the API.
Simple, transparent pricing
Flux charges a flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume merchants and no setup fees or contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee. You can also pass the processing fee to the customer at checkout where local surcharging rules allow.
Frequently asked questions
Does the card capture form charge the customer?
No. It collects and stores the card tokenized, and nothing is charged until you charge it.
Is the captured card stored securely?
Yes. The form uses PCI-compliant hosted fields and the card is tokenized in the Flux vault, so your systems never hold the number.
When would I use a capture form instead of a payment link?
Use a payment link to get paid now. Use the capture form to get a card on file for deposits, incidentals, or billing that starts later.
