"Device for data transmission from a transponder to

a cell phone"

The innovation relates to a device according to the preamble of claim 1.
10

Such a device is known from DE 295 18 675 U1.

Barcodes can be copied and thus made available to unauthorized persons.

The barcodes can become dirty, so that malfunctions when reading the data from the barcodes cannot be ruled out.

The innovation is based on the task of creating a generic

to improve the device in question so as to enable improved security of data transmission.

The object of the invention is achieved by a device having the features of claim 1.

In other words, the innovation proposes using a transponder reader instead of a barcode reader. According to the innovation, the term "transponder" is not only used in its technical meaning, but the innovation also

generally applies to a wireless, non-optical transmission technology for communication with a memory chip. The devices, known in technical terms as "transponders", however, have the advantage of requiring little space and low manufacturing costs and are preferred. In addition,

They are passive transponders without the need

a permanently installed power supply in almost any location. When reading their memory content, they extract the required energy wirelessly from the transponder reader via the electromagnetic field it creates.

Transponders can be installed invisibly so that, depending on the application, unauthorized persons do not notice the presence of the transponder and therefore copies of the stored signals are not possible. In addition, special

For a more secure way, the data can also be stored using cryptographic technology, so that unauthorized persons can hardly access the data even when the transponder is read. Since the data cannot be seen visually, contamination does not affect operational safety.

The transponder reader can be connected to an interface of an existing radio telephone using a transmission cable. However, both the transponder reader and its connection means can advantageously be connected to the electronics of the

The radio telephone can be located directly in the housing of the radio telephone. This creates a reliable and easy-to-use service device with which the data can be read in and immediately transmitted to a control center.

The transponder reader can also be advantageously designed as a combined reading/writing device. In this way, data can be stored in the transponders.

e.g. for transportable goods with specified maintenance

cycles, such as gas bottles, the number of fillings carried out can be stored in the transponder of the gas bottle or usage data from machines can be stored in such transponders, whereby the reading of this data can provide clues for certain measures such as

·■

Replacing or checking gas bottles, the extent of maintenance work on machines, etc.

In the case of delivery services, items to be delivered can be provided with such transponders so that

of an item by a delivery company, the delivery can be immediately registered at a central office through data transmission by radio telephone and an invoice can be created.

For example, in the case of security services or services at large industrial facilities, there is also the option of time recording: The transponder contains a specific identifier for the location or for a specific machine; this identifier is read in and associated with the time and date by the radio telegram.

fon to a central office.

With standard mobile phones, the data can be sent cost-effectively as a so-called "Short Message Service" without the need to set up a separate radio service.

take place.

An electronic circuit can be included in the data exchange between the control center and the radio telephone, so that, for example, in the case of security services, certain intervals between

between two control points and are provided with a certain time tolerance value. For example, if the identifier of the transponder of the first control point is transmitted to the control center along with the time, it can be provided that after a certain time period the identifier

of the second control point should be transmitted to the headquarters.

If this specified time is exceeded by a certain tolerance level, either an automatic alarm message

or a call can be made from the control center to the radio telephone.

A radio connection must be established. If this call from the control center is not answered by the security staff within a specified time and, for example, by entering a multi-digit code number, an automatic alarm can be triggered.

According to the innovation, the control points can be hidden, that is to say, invisibly installed in building walls or behind panels, so that it is almost impossible for unauthorized persons to collect data from the transponders. By using the

Cell phones eliminate the need for a fixed connection, which is usually accessible from outside by unauthorized persons and can be disrupted, thus improving the security of data transmission.
