A contactless card useful for adjusting the operation, configuration, and/or performance of a secondary device is described. The contactless card is equipped with a communication interface which allows the contactless card to transmit information to the secondary device using NFC signals. The contactless card stores accommodation information related to a physical accommodation desired by the user and transmits that information in the form of an accommodation message to the secondary device after being placed in a NFC field generated by the secondary device. In some embodiments, the contactless card requests an authentication certificate in order to determine a degree of trust prior to sending an accommodation message. In some embodiments, the contactless card may adjust what accommodation information is included in the accommodation message based on the authentication certificate received from the secondary device.
