@AMJohnson and @krobinson flagged that we receive AmEx bank rejections from India, where AmEx is not accepted,. The IN form doesn’t list card types or show card logos.
Would it be possible to have the IN form validate on AmEx BINS to advise the donors that AmEx is unaccepted / ask them to use a different card before they submit their attempt? The volume of donors affected is small, less than a dozen a month, but it would save donors frustration and reduce rejections at Gravy.
