Abstract: A bracelet including a plurality of circuits. The plurality of circuits includes a wireless communication circuit configured to communicate with a first device, a near-field communication circuit configured to communicate with a second device via a near-field communication antenna, and a power supply circuit including a battery. The first device is remote from the bracelet. The power supply circuit is configured to supply power to one or more of the plurality of circuits.

Abstract: Some of the embodiments of the present disclosure provide method for initializing an extension device that acts as an extension of a communication device for communicating with a near field communication (NFC) device, wherein the NFC device operates in accordance with NFC standards, the method comprising discovering, by the communication device, the extension device over a first wireless communication link, wherein the first wireless communication link is a Bluetooth communication link; receiving, by the communication device, a default password associated with the extension device; and in response to receiving the default password associated with the extension device, configuring, by the communication device, the extension device such that the extension device communicates (i) with the communication device over the first wireless communication link and (ii) with the NFC device over a second wireless communication link. Other embodiments are also described and claimed.
