US 9,071,282 B1 · Variable read rates for short-range communication

Abstract

In general, techniques and systems for selecting a read rate for short-range communication with a computing device are described. In one example, a method includes detecting, by a computing device, a trigger event. The method may also include, responsive to the detection of the trigger event, changing a near-field communication (NFC) read rate from a first read rate to a second read rate by multiplying the first read rate by a predetermined value. The method may also include generating, by the computing device, NFC signals at the second read rate. In some examples, the trigger event may include an acceleration or velocity of the computing device exceeding a threshold, detecting the computing device within a predetermined geographical location, or detecting an ambient light intensity exceeding a threshold.

A method comprising:

detecting, by a computing device, a trigger event;
responsive to detecting the trigger event, changing, by the computing device, a near-field communication read rate from a first read rate to a second read rate by multiplying the first read rate by a predetermined value;
and
generating, by the computing device, near-field communication signals at the second read rate,
wherein the near-field communication read rate defines a number of times the near-field communication signals are generated within a time period, and
wherein detecting the trigger event comprises at least one of detecting a value sensed by the computing device exceeding a threshold, receiving information from a near-field communication device, or receiving a command from an application executing at the computing device that instructs the computing device to change the near-field communication read rate.
