How to deal with Eximbay payment errors If the error code starts with TS as below, the error is occurring due to 3DS payment error. - TS: 3DS (payer authentication , 3d secure authentication) error code - TS01: 3D – Not Enrolled. - TS02: Cardholder Authentication Unavailable. - TS03: Error - TS21: Authentication is not completed. - TS22: Customer was presented with the authentication screen however either clicked the "exit" option or was unable to provide the correct password. 3DS is a system in which payment is approved by entering card information and then self-authenticating unlike the normal payment process of entering the card number, expiration date and CVC in the payment screen. The payment pop-up message is exposed if the purchaser hasn’t signed up for the 3DS authentication service. If one wishes to sign up for it, they must contact the credit card company directly. If the Eximbaby 3DS payment error persists, please note that one can make a payment using PayPal.
