Abstract

A method for managing the communication between a communication portable device (200) including a NFC device and a NFC tag (100) including a plurality of information, comprises comprising determining a position and/or orientation of the communication portable device (200) and enabling the communication portable device to read a portion of the plurality of information units, depending on the position and/or orientation of the communication portable device.

Claims

1. Method for managing the communication between a communication portable device including a NFC device and a NFC tag including a plurality of information, the method comprising determining a position and/or orientation of the communication portable device and enabling the communication portable device to read a portion of the plurality of information units, depending on the position and/or orientation of the communication portable device.

2. Method according to claim 1, wherein the method comprises determining the orientation of an axis of the communication portable device.

3. Method according to claim 2, wherein the method comprises discretizing a round angle in a plurality of angular sectors, the number of angular sectors being equal to the number of information units comprised in the NFC tag, associating each angular sector to one information unit, recognizing the angular sector towards which the axis of the communication portable device is oriented, reading the information unit associated to the recognized angular sector.

4. Method according to claim 2, wherein the step of recognizing the angular sector includes acquiring an angular zero reference from the NFC tag and measuring the angular distance between the angular zero reference and the axis of the communication portable device.

5. Method according to claim 4, wherein the angular zero reference is a physical mark on the NFC tag.

6. Method according to claim 4, wherein the angular zero reference is acquired by orienteering the communication portable device parallel to one of the edges of the NFC tag.

7. Method according to claim 4, wherein the angular zero reference is a vertical axis of a location where the NFC tag is installed.

8. Communication portable device including:

a NFC device configured for reading a plurality of information from a NFC tag,

a sensor for determining a position and/or orientation of the communication portable device,

a controller associated with the NFC device for enabling said NFC device to read a portion of the plurality of information, depending on the position and/or orientation of the communication portable device.

9. Communication system including a communication portable device according to claim 8 and at least a NFC tag including a plurality of information units.
