Abstract

The invention relates to an electronic device (10) with a Near Field Communication (NFC) interface, and a method for accessing data using NFC. The NFC interface of the electronic device is positioned within communication range of a second NFC interface of a second device, whereby data is transferred to the first electronic device from the second electronic device. The data is sorted into a layered data structure including at least two layers, wherein a first layer includes directly presentable first information, such as brief content description, and a second layer includes a communication address to an information source accessible by means of a network connection to download further information.

Claims

1. Method for accessing data, comprising the steps of:

providing an electronic device having a Near Field Communication (NFC) interface with an antenna connected to a demodulator for acquiring data modulated in an electromagnetic wave, and a second communication interface connectable to a network;

positioning the NFC interface within communication range of a second NFC interface of a second device;

receiving data in the first electronic device from the second electronic device, which data is sorted in at least two layers, wherein a first layer includes directly presentable first information, and a second layer includes a communication address to an information source.

2. The method of claim 1, wherein the data is sorted in at least three layers, where the second layer comprises a communication address to a public information source, and a third layer comprises a communication address to a personal network information source.

3. The method of claim 1, comprising the steps of:

detecting if the electronic device is connected to a network;

presenting only the first information if the electronic device is not connected to a network.

4. The method of claim 1, comprising the steps of:

detecting if the electronic device is connected to a network;

storing the communication address in a memory of the electronic device if the electronic device is not connected to a network.

5. The method of claim 1, comprising the steps of:

detecting if the electronic device is connected to a network;

accessing the information source to retrieve information if the electronic device is connected to a network.

6. The method of claim 1, wherein the second layer comprises URL information.

7. The method of claim 2, wherein the third layer comprises file name information.

8. The method of claim 1, wherein the first information of the first layer includes an identification of content accessible using the communication address of the second layer.

9. The method of claim 1, wherein the NFC interface operates in the 13.56 MHz frequency band.

10. Method for providing data using a Near Field Communication (NFC) tag, comprising the steps of:

storing directly presentable first information in a first layer in a memory of the NFC tag;

storing a communication address to an information source in a second layer in the memory;

modulating an electromagnetic wave to include the data of both layers as a layered data structure;

transmitting the modulated electromagnetic wave using an antenna of the NFC tag.

11. The method of claim 10, comprising the steps of:

receiving an electromagnetic wave in the antenna, wherein the step of modulating includes

performing load modulation to include the data of both layers as a layered data structure.

12. The method of claim 10, wherein the NFC tag operates in the 13.56 MHz frequency band.

13. The method of claim 10, wherein the data is sorted in at least three layers, where the second layer comprises a communication address to a public information source, comprising the steps of:

storing a communication address to a personal network information source in a third layer in the memory;

modulating the electromagnetic wave to include the data of all layers as a layered data structure.

14. The method of claim 10, wherein the second layer comprises URL information.

15. The method of claim 13, wherein the third layer comprises file name information.

16. The method of claim 10, wherein the first information of the first layer includes an identification of content accessible using the communication address of the second layer.

17. A Near Field Communication (NFC) device, comprising:

an antenna for sensing an electromagnetic wave,

a circuit including a modulator connected to the antenna for incorporating data in an electromagnetic wave;

a memory connected to the circuit, said memory including a layered data structure including

directly presentable first information in a first layer, and

a communication address to an information source in a second layer.

18. The NFC device of claim 17, wherein the layered data structure includes

a communication address to a public information source in the second layer, and

a communication address to a personal network information source in a third layer.

19. The NFC device of claim 17, wherein the circuit comprises:

an electromagnetic wave generator for forming a radio frequency field, connected to the antenna.

20. The NFC device of claim 17, wherein the circuit comprises:

a demodulator connected to the antenna for acquiring data modulated in an electromagnetic wave.

21. The NFC device of claim 17, wherein the circuit comprises:

a load modulator configured to modulate an electromagnetic wave received by the antenna to incorporate data in the electromagnetic wave.

22. The NFC device of claim 17, wherein the second layer comprises URL information.
