How can I validate credit card number?

hello sir ,,

how can i check credit card number is valid or not without adding payment method ??

thanks ,,

Unfortunately, there is no widget currently available to validate the credit card number. Please note that collecting credit card using plain text fields is not allowed with JotForm and such forms are considered as phishing forms. Please refer to terms of usage for more information on phishing forms. In order to validate the credit card number, the only way is to enable payment authorization with the payment field viz., PayPal, Authorize.net, Square and Stripe. Please refer to the guide below that can help you with this.
