First Claim
Patent Images
1. A method for managing communication between a contactless reader and a portable device, said contactless reader being able to communicate using a first wireless technology configured to communicate in a short-range mode,wherein the method comprises the following steps:
- establishing a first communication channel between the contactless reader and a wireless unit,establishing between the wireless unit and the portable device a second communication channel using a second wireless technology, said second wireless technology being an Ultra-Wide Band protocol which is configured;
to operate with a range greater than that of said first wireless technology,to detect the position of the portable device with respect to the wireless unit,to handle an anti-collision phase, andestablishing a bridge between the contactless reader and the portable device through said first and second communication channels only if the detected position of the portable device is located in a preset physical area associated with the contactless reader.

Abstract
The invention is a method of managing communication between a portable device and a contactless reader able to communicate using a first wireless technology configured to communicate in a short-range mode. The method comprises the steps of:
- establishing a first channel between the contactless reader and a wireless unit,
- establishing between the wireless unit and the portable device a second channel using a second wireless technology which is configured:
- to operate with a range greater than that of said first wireless technology,
- to detect the position of the portable device with respect to the wireless unit,
- to handle an anti-collision phase,
- establishing a bridge between the contactless reader and the portable device through said first and second channels only if the detected position of the portable device matches with the contactless reader.
