Thredd has relationships with existing card manufacturers, who we can instruct to print your cards. We use Secure FTP (sFTP) to send the card manufacturer a generated bulk XML file containing card details. This is sent on a daily basis, or at a frequency that can be customised for your service. The card manufacturer prints the cards and sends to the cardholder. Any white label test cards are typically sent to Thredd , the Program Manager and the Card Schemes.
For a list of supported card manufacturers, see the Web Services Guide.
