This provides a way for the merchant ( channels Provider: Regular or Value Financing ) to securely collect card details for customers paying with debit or credit card to complete the loan application on their channels. It enables the merchant to control the experience; look and feel (that is, the merchant is in complete control of their UI/UX).
The following fields are hosted securely in iframes which the merchant can embed in their checkout page;
- PAN
- Expiry Date
- PIN
- CVV
- OTP

Create Hosted Fields Instance
Create an instance of hosted Field by Calling the newInstance method on the interswitch.hostedFields variable , the method takes options and a callback.
The create instance can be used to register events listeners and finally submit the customer’s request when the customer clicks on a the submit button. On submit this instance will return to the callback.
