Why Veryfi

On-device · No API call · PCI compliant

Credit card in. JSON out.

Veryfi’s Credit Card Capture SDK reads both sides of a payment card on the phone and returns the number, name, expiry, brand, and CVC as JSON. There is no API call. The capture is PCI compliant because the image and the PAN stay on the device. Wallets, checkout, and card-on-file flows use that JSON instead of a 16-digit form. See supported card fields and the Lens for Credit Cards docs.

What is a credit card?

A credit card is a payment card. The front carries the primary account number, the cardholder name, the expiration date, and the network brand. The back carries the verification code — CVV, CVC, or CID.

Checkout and wallet apps need those same values as data. The SDK reads both sides on the device and returns that card as JSON. There is no API call. The capture is PCI compliant, and the number never leaves the phone.

Did you know

The last digit is a check digit. Change any other digit and the number fails the Luhn test, which is how a blurry read can be rejected before anyone tries to charge it.

Features

  • On-Device Processing

    All credit card image processing and data extraction is performed entirely on the device, without being sent over the internet.

  • Card Detection

    Veryfi Lens runs a light machine model to perfect the capture of your customers' credit cards. Veryfi Lens runs a machine model which is trained to distinguish a credit card from its surroundings, including other hard edges and similarly colored surfaces. This means there is no need for guides or messages in app to tell your customer how to position the card. They can hold it in their hand or on any surface and the machine model inside Veryfi Lens will identify the card and extract all the data on both sides. This makes the experience of capturing card information super seamless and pain free.

  • Auto Torch in Low Light

    Veryfi Lens includes Al computer vision and custom camera features that optimize image quality based on surroundings to ensure the greatest possible data extraction accuracy. The real-time Veryfi Lens computer vision model recognizes low light situations and automatically enables the device’s torch/flashlight to ensure high-quality credit card capture.

  • Auto Capture

    Veryfi Lens can be configured to automatically capture the credit card without pressing the capture button. The machine model inside Veryfi Lens will calculate when it sees the card to automatically snap the picture for you ready for your preview. Technology should make your customer's life easier, not harder.

  • Headless Mode

    You can take advantage of all the AI and machine model without the default graphical user interface that comes prepackaged with Veryfi Lens. This way you can control the UI/UX experience while still providing powerful AI features to your customers.
