According to the user manual, the Answer to Select (ATS) value for the ACOS3 Contactless card can be customized, but this customization can only be done at the ACS production facilities. If you require a custom ATS value, you should contact your ACS representatives during the ordering process. The manual also mentions that for Microsoft Windows usage, if the operating system attempts to download a smart card minidriver for the ACOS3 Contactless card, you can disable smart card plug and play and certificate propagation in Windows or use ACS's Unified Null Driver. For more information on customizing the ATS value or resolving driver installation issues on Windows, it is recommended to contact your ACS representative for assistance.
