Method of power negotiation between two contactless devices |
摘要 |
The invention is a method of power negotiation between a first contactless device and a second contactless device which provides an electromagnetic field set to a first power level. The method comprises the steps of: a) sending a request from the first device to the second device. The request targets a second power level and an associated duration. The next step is: b) sending a response to the first device. The response reflects a decision of the second device corresponding to the request. The final step is: c) switching the electromagnetic field to the second power level if the decision is positive.
