1. A device for contactless communication with a terminal, comprising:
an antenna for communication with the terminal;
an embedded chip configured to communicate with the terminal in accordance with a contactless transmission protocol whereby a message sent by the terminal to the embedded chip sets a specified initial waiting time for a response from the embedded chip to the terminal to maintain a connection with the terminal, the embedded chip being configured to communicate requests to the terminal to extend the waiting time for response; and
a module configured to perform processing formed of a plurality of discrete operations, wherein the module is a biometric sensor module and the plurality of discrete operations is a plurality of biometric authentication steps,
the module being configured to, in response to completing a subset of one or more discrete operations within a waiting time interval set by the terminal, send a first type of command to the embedded chip if the module determines the processing is not complete and send a second type of command to the embedded chip if the module determines the processing is complete, and
wherein the embedded chip is further configured to, in response to receiving the first type of command from the module, communicate a request to the terminal to extend the waiting time for response.
