Credit Card Validation

I recently installed this plugin and it has worked great so far. However, I noticed that it doesn’t validate the credit card field (integrated with Stripe). An old issue (2+ years ago) says that this feature had not yet been implemented at the time, but was planned for the future. Though credit card fields are not listed in the “supported fields” section in the plugin description, I wanted to make sure this feature has not yet been implemented before I look into alternative validation options.

Thanks in advance for your help!
