Abstract
In some implementations, a mobile device includes a first interface configured to communicably couple to a removable integrated circuit card; a second interface configured to wirelessly communicate with a contactless reader that is external to the mobile device; a communication interface that couples the first interface and the second interface and that is configured to obtain information from an integrated circuit card that is coupled to the first interface in response to receipt by the second interface of an information request from the contactless reader; and a programmable timer that is configured to be started in response to the second interface receiving an information request from the contactless reader, and that is further configured to, upon reaching a programmed value, cause the second interface to transmit the obtained information to the contactless reader.
