Method of communication of an active smart RFID label with a user interrogator and a professional interrogator
A method of communication of an active smart RFID label with a user interrogator and a professional interrogator, said professional interrogator enabling a service provider to fully control said active smart RFID label and by means of which interrogator a content and a form of an extract of data, which are collected by a sensor, which is comprised of in the label, as well as a location within the label as location of said extract of data being collected by said label sensor, said location being accessible by the user interrogator are determined. A service user gets concisely acquainted with the service provided by the label by means of a widely used interrogator, whereat he cannot influence the data contained in the label or even its functioning neither needs any additional knowledge to communicate with said label.
1. A method of communication of an active smart radio-frequency identification (RFID) label with a user interrogator being a portable telephone provided with a near field communications (NFC) module and a professional interrogator, said professional interrogator enabling a service provider to fully control said active smart RFID label in that said professional interrogator can access all data therein, load data into said smart RFID label and set parameters of said smart RFID label's operation, the method:
characterized in that the professional interrogator determines a content and a form of an extract of data, which are collected by a sensor, the sensor being comprised by the active smart RFID label,
characterized in that the professional interrogator determines a location within the active smart RFID label, which location is accessible by the user interrogator, as the location where said extract of data being collected by said label sensor should be entered,
characterized in that the user interrogator has access to the extract of data and cannot fully control the active smart RFID label, and
characterized in that said active smart RFID label determines the type of a first interrogator as being a user interrogator or professional interrogator depending on an RFID protocol used by said first interrogator, whereat the first interrogator, which established a contact communication with the smart RFID label, is recognized as user interrogator or as professional interrogator, depending on a command received from said first interrogator or depending on a frequency of a signal, which said first interrogator uses for communication with said smart RFID label.
2. The method as recited in claim 1 , characterized in that the user interrogator operates at a frequency of 13.56 MHz.
3. The method as recited in claim 1 , characterized in that the user interrogator operates in the ultra high frequency (UHF) frequency range.
4. The method as recited in claim 1 , characterized in that the professional interrogator determines a location in said active smart RFID label, into which a user can enter a demand.
5. The method as recited in claim 4 , characterized in that the service provider reads a user's demand by means of the professional interrogator and enters a decision on the user's demand into said active smart RFID label.
6. The method according to claim 1 , characterized in that the professional interrogator determines a location within said active smart RFID label, into which location a user can enter data.
7. The method as recited in claim 1 , wherein the user interrogator cannot access all data stored in the active smart RFID label.
