Hello! Sometimes expired card will work, so we make the attempt. I don't believe there's a setting to enable strict expiration validation. You would either need to write code to do that, or possibly use a custom Radar rule.

#

We use the PaymentSheet, so don't validate locally on the iOS/Android apps.

#

What is Radar rule?

#

Also we do auth and then charge after an Ev charge.

You can write custom Radar rules to block charges (but this is a paid feature): https://stripe.com/docs/radar/rules

I don't see anything specific for expiration in the docs.

Let me have a look. I don't think I've ever tried to write a rule for something like this before.

Is bad expiration a problem? We are about to launch the 1.0 of iOS/Android apps.

#

It's not really a problem in general, no. Most of our surfaces will reject an expiration date in the past, for example, and I believe that includes the PaymentSheet. As far as entering it incorrectly it will either work anyway, or the card issuer will decline which will, in turn, prompt the customer to enter the correct date.
