Trouble with Amex payment

[Lager]

After entering the total amount and the card info for an Amex card, Square says payment failed something went wrong.  The same process works fine for Visa and M/C.  I am certain the card is OK.  What am I doing wrong?

Hi Lager,

Unfortunately we can only guess - if you're manually entering the card details, other than the card number, security code, expiration date and Zip Code and assuming those details are correct - if it's not accepted, in most scenarios, the issue on the customer's side or bank.  There can be multiple reasons, but there's no way anyone here would know the exact reason.  Did you get any error codes or messages ?   Also, if you check this site, there have been no Square System issues reported.
