AI Technical Summary

Problems solved by technology

This problem may be compounded by the fact that additional functions may consume more power and / or take a longer period of time than the main function of the card
Another problem is that for cards operating in contactless mode, the power drawn by the additional functions may affect the load modulation of the signal sent by the terminal, which may introduce additional noise to the terminal

Embodiment Construction

[0067] The following description and drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.

[0068] The present disclosure relates to a device for contactless or contact communication with a terminal. The device includes: an antenna for receiving wireless signals sent by a terminal; an embedded chip (such as an integrated circuit chip) and an additional embedded module. Modules are (logically and / or physically) separate from chips; for example, they may be distinct components each embedded within a device. The chip generates data for communicating with the terminal to perform a first function associated with the device. This first f...

Abstract

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.

Description

technical field [0001] The invention relates to the architecture of a multifunction device. In particular, certain aspects relate to the architecture of devices capable of operating in a contactless mode of operation. Background technique [0002] A smart card may refer to a device that includes an embedded integrated circuit chip and internal memory. This internal memory can be located on an integrated circuit chip, or a separate chip embedded in the card. A smart card may be a contact card; a contactless card, or may be capable of operating as a contact and contactless card. Smart cards exist in a variety of form factors, including plastic cards, key fobs, watches, wearables, electronic passports and USB-based tokens and subscriber identity modules (SIMs) used in mobile phones. [0003] A contact card communicates with a terminal (eg, a card reader) by physically connecting to the terminal. For example, a contact card may include one or more contact pads that provide a...
