Yes

#

then what does it mean to attach a new card payment method to a customer?

#

https://stripe.com/docs/disputes/prevention/verification#:~:text=You can perform CVC verification by providing the CVC value either when you create a payment with a new card payment method%2C or when you attach a new card payment method to a customer.

minor bison Mar 15, 2023, 2:28 AM

#

Meaning that you can save the payment method to a customer with Stripe while collecting the payment method

#

ah so when you come back to the same store they can use the card on file?

minor bison Mar 15, 2023, 2:28 AM

#

Yes!

#

You may refer to the doc here: https://stripe.com/docs/payments/save-during-payment

#

at which you can re-request the cvv again for verification

minor bison Mar 15, 2023, 2:29 AM

#

If the card saved on file is used, Stripe doesn't ask CVC again

sick socket Mar 15, 2023, 2:30 AM

#

but cant we request it if some info has updated

#

we want to require re-entry at the time of updating shipping address

#

i guess thats something we can do on our side but im just asking if thats possible

#

nvm i found it

#

what actually happens when cvv2 is entered? what does stripe forward to the issuing bank ?

#

You may re-collect CVC with the guide here: https://stripe.com/docs/payments/save-during-payment-cards-only#web-recollect-cvc

#

what actually happens when cvv2 is entered? what does stripe forward to the issuing bank ?
Yup! CVC will be sent to the card issuer

sick socket Mar 15, 2023, 2:37 AM

#

so card# + expiration date will be automatically updated with card account updater and if cvv2 is required, itll prompt for re-entry at which Stripe sends just the cvv2 to card issuer for verification?

minor bison Mar 15, 2023, 2:47 AM

#

Stripe will not prompt to collect CVC even when the card is updated automatically. Re-collecting CVC should be implemented by your application if you think re-collecting CVC is required. If CVC is collected by your application and sent to Stripe, CVC will be sent to the card issuer

#

not sure if youd know but is there a fee for CVC verification? I mean its to minimize fraud therefore should lower IC fees, yeah?

#

and if we require CVC(set fraud rule to block) we would need to verify each time since CVC doesnt save, correct?

This channel is for technical integration, so we don't know much about fees. I'd recommend checking with Support https://support.stripe.com/contact about this

Yes! CVC can't be saved. It should be collected every time when needed

sick socket Mar 15, 2023, 3:21 AM

#

ok if required...itll automatically prompt to re-enter therefore recollect a CVC wouldnt be necessary?

minor bison Mar 15, 2023, 3:26 AM

#

Stripe doesn't automatically prompt to re-enter CVC. If you wish to re-collect CVC, it has to be implemented in your application

ok got it thank you
