Abstract
Method, device and system for data transfer between a mobile device (3) and a reader device (2), the method of data transfer comprising: transmitting (S3) a request value from an ultra-wideband communications module (1) to the reader device (2); determining (S4) a distance between the ultra-wideband communications module (1) and the reader device (2); generating (S5) a validation value in the reader device using the request value and transmitting (S6) the validation value from the reader device (2) to the mobile device (3), if the distance is smaller than a predefined value; verifying (S7), in the mobile device (3), the validation value; and enabling (S8), in the mobile device (3), further data transfer (S9) between the mobile device (3) and the reader device (2), upon affirmative verifying of the validation value.
