Can I send you my updated Credit Card Number by Email???
There is only one answer to this question
NO: NEVER EVER SEND CREDIT CARD NUMBERS BY EMAIL.
Can not say more than that.
My Credit Card number didn't change, but just my expired date changed; Can't I just email you this information?
You could, but see the answer above. Even if you did, we can't update your information. We can't see your credit card number. All Credit Card Number are blanked out for security.
To do any updating of Credit Card Number, requires that the credit card number be enter as well as the expiring date.
Security prevents just changing the Card Expired date.
