Process and system for automatically updating data recorded in a radio frequency identifier
The invention is intended to be used in the technological field of communication and the update of data between electronic equipment ( 1, 2 ) capable of inter-communicating using wireless links. The invention relates more particularly to a process and a system to automatically configure and update the data saved in a radio frequency identifier ( 3 ). The process and the system enable the update of the data recorded in a radio frequency identifier of a first equipment item ( 1 ) equipped with a display screen ( 5 ) by displaying on screen a visual code ( 7 ) bearing update data of the radio frequency identifier. The visual code is then read using a second equipment item ( 2 ) provided with a visual code read device ( 4 ) having radio frequency identifier read-write interface. Then, the decoding of the visual code and the conversion and transmission of the update data to the radio frequency identifier by means of the read-write interface are performed.
1. A process of updating data recorded in a first radio frequency identifier comprised in a first equipment item, the first equipment item being provided with a display screen, the process comprising the following steps:
a) sending to the first equipment item, by a first link enabling a connection of the first equipment item in a network, a visual code that contains some update data intended for the first radio frequency identifier comprised in the first equipment;
b) displaying the visual code bearing the update data of the radio frequency identifier on the display screen;
c) using a second equipment item comprising an image sensor and a visual code read device, the visual code read device having a second radio frequency identifier read-write interface for reading the visual code with said second radio-frequency identifier read-write interface, after an image of the visual code displayed on the display screen has been captured with the image sensor of the second equipment item;
d) decoding the visual code captured with the second equipment item, converting the decoded visual code into the update data, and transmitting the update data to the first radio frequency identifier by means of the second radio frequency identifier read-write interface and a second radio communication link.
2. The process of updating data according to claim 1 , wherein the visual code also comprises the data of a program executed on the second equipment item, the program comprising automatic execution instructions of step d) of claim 1 .
3. The process of updating data according to claim 1 , wherein the visual code is a barcode, or a two dimensional code.
4. The process of updating data according to claim 1 , wherein the update of the data is an update of a content of identification data of the first equipment item, the identification data being recorded in a memory of the first radio frequency identifier.
5. The process of updating data according to claim 1 , wherein the update of the data is an update of a content of encryption data, the encryption data being recorded in a memory of the first radio frequency identifier.
6. The process of updating data according to claim 1 , wherein the update of the data is an update of hardware configuration data specific to a physical processing or storage units of data of the first equipment item, said hardware configuration data being recorded in a memory of the first radio frequency identifier.
7. The process of updating data according to claim 1 , wherein the update of the data is an update of hardware configuration data specific to an equipment capable of being connected to the first equipment item, said hardware configuration data being recorded in a memory of the first radio frequency identifier.
8. The process of updating data according to claim 1 , wherein the update of the data is an update of software configuration data specific to a software implemented by the first equipment item, said software configuration data being recorded in a memory of the first radio frequency identifier.
9. The process of updating data according to claim 1 , wherein the first radio frequency identifier is a RFID (Radio Frequency Identification) transponder.
10. The process of updating data according to claim 1 , wherein the visual code read device and the second radio frequency identifier read-write interface comprised in the second equipment item form an active RFID transponder that can transmit radio waves to read and write digital data recorded in a RFID transponder comprised in the first equipment item.
11. The process of updating data according to claim 9 or 10 , wherein the RFID transponder of the first equipment item and the active RFID transponder of the second equipment item are of a NFC (Near Field Communication) type.
12. A system to implement the process of updating data according to claim 1 , the system comprising a first equipment item provided with a display screen and a first radio frequency identifier; a second equipment item provided with an image sensor and capable of transmitting some digital data to the first equipment item by a radio communication, the second equipment item comprising a second radio frequency identifier read-write interface device to update the digital data recorded in the first radio frequency.
13. The system according to claim 12 , wherein the first equipment item is a photographic kiosk or a printer.
14. The system according to claim 12 , wherein the second equipment item is a digital camera or a digital phonecam.
