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 sets a specified initial waiting time for a response from the embedded chip 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, 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 processing is not complete: wherein the embedded chip is further configured to, in response to receiving the first type of command, communicate a request to the terminal to extend the waiting time for response.

Device with biometric process synchronization

A two-wire interface () for connecting a first device () and a second device (). The two-wire interface () is operable in a handshaking mode and a data transfer mode. In the handshaking mode the first wire () of the interface () is driven by the first device () and the second wire () of the interface () is driven by the second device () so that the first () and second () devices can perform a handshaking sequence. In the data transfer mode one of the first wire () and the second wire () is driven by one of the first () and second () devices to provide a clock signal, and the other wire is driven by either the first device () or the second device () depending which device is transmitting data. Accordingly, the two-wire interfaces () are operable in two modes (e.g. handshaking mode and data transfer mode) and one of the wires () of the interface () may be driven by a different device in the two modes.

Two-wire host interface

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 sets a specified initial waiting time for a response from the embedded chip 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, 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 processing is not complete; wherein the embedded chip is further configured to, in response to receiving the first type of command, communicate a request to the terminal to extend the waiting time for response.

Device process scheduling

A device for contactless communication with a terminal, the device comprising: an antenna for receiving a wireless signal emitted by the terminal; an embedded chip configured to generate data for communication to the terminal to perform a first function associated with the device; and a module separate from the chip configured to perform processes as part of a second function associated with the device, the module being connected to the antenna and comprising a power-harvesting unit configured to harvest power from the received wireless signal to power at least the module.

Device architecture

A device comprising: an antenna; a power harvesting circuit for harvesting power from a radio frequency field received at the antenna in order to power functions of the device; a communication unit coupled to the antenna for transmitting and receiving signals by means of the antenna, the communication device being configured to communicate according to a protocol in which a party to a communication session deems the session to have timed out if during a predetermined period it does not receive a signal from another party to the session; and a module comprising a processing circuit; the device being configured to interrupt the operation of the module when the communication unit is transmitting a signal by means of the antenna.
