Definitions

  • the invention relates to a transponder which emits data stored in it after receiving a readout signal.
  • the invention relates to a method for reading data from a transponder.
  • Transponders are - mostly wireless - communication, display or control devices that receive incoming signals and automatically respond to them. They can be passive or active. Passive transponders are understood to be systems that derive the energy needed to communicate and process internal processes solely from the field of read / write units, such as, e.g. RFID (Radial Prequency] Edentification) transponders. Such RFID transponders are usually attached to goods and contain for the identification of this product stored data. As a result, it is possible to investigate buyer habits by reading the RFID transponders on the goods.
  • the invention is therefore based on the object of specifying a transponder with readout protection and an associated method in which unwanted reading out of data is avoided.
  • the first object is achieved by a transponder having the features of claim 1.
  • a solution to the second task is indicated by the method according to claim 6.
  • Transponders are mostly mobile devices that are requested to output or to send data stored in it due to a received read-out signal. This is also true for RFID (Radial Frequency Identification) transponders, e.g. Receive a read-out signal from a read / write device via radio and then usually respond with the transmission of data.
  • RFID Radio Frequency Identification
  • such transponders are provided with a read-out mechanism which effects the transmission of the data only after a PAUSE following the reception of the read-out signal.
  • the interpretation mechanism can be activated, so that when a read signal is received, the data stored in the transponder is not read out immediately, but only after a certain, settable time. This can be done by means known to those skilled in the art, e.g. corresponding to the discharge of a capacitance, by means of a shift register or e.g. with a counter with external stimulated clock of defined length.
  • the PAUSE duration can be controlled by one or more internal and / or external parameters.
  • Internal parameters include setting a
  • PAUSE flags of authorized persons and setting the PAUSE duration above predefined values e.g. using a PAUSE register.
  • field strength, temperature, humidity, water, oxygen, etc. can be used as external parameters.
  • the flowchart shown in the figure shows the essential steps of the method according to the invention for Protected readout of data of a transponder.
  • Receives the transponder by receiving a read-out signal the request to read out stored data, it is first queried whether the read-out mechanism is activated in the transponder. If this is not the case, the data are immediately discontinued, otherwise this is done after a presettable PAUSE duration.
  • the response within a read cycle can be delayed. After the magnetic reading field is applied, the transponder responds only after n seconds. The answer can also be made only at the next, after the next or a later Auslese pulp. For each attempt, the register is decremented by one.
