Container for receiving articles

Abstract

The invention provides a container (10) comprising a, a receiving compartment (18) for receiving articles (12) each provided with an RFID transponder (14), a shielding (16) for shielding of the receiving compartment (18), and an RFID antenna device (20) located in the receiving compartment (18) for communication with the transponders (14). Reliable identification of articles (12) located in the container (10) can thus be simplified considerably.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a container for receiving articles such as, for example, a shopping cart for receiving goods, a sea freight container for transporting goods, a roll container which can be used in passenger aircraft for holding food and drink, a “rack” (e.g. IT server rack) for installing electrical and electronic devices etc.[0003]In many areas of application it is desirable to be able to detect and identify articles actually accommodated in a container as simply and rapidly as possible.[0004]2. Description of the Prior Art[0005]RFID (“radio frequency identification” is a known technique for wireless identification of objects which has been used for some time in the area of so-called auto-ID, i.e. the automatic supply of information to persons, animals, goods, and articles.[0006]Each auto-ID system is based on using artificial identification features to allow machine identification. The barcode labels s...

AI Technical Summary

Benefits of technology

[0017]Surprisingly, the very disadvantageous effects of a shielding in the prior art are transformed into a series of serious advantages in the invention. A first advantage, for example, consists in that the antenna device (comprising one or more antennae) is located in the immediate vicinity of the articles (and therefore transponders) without interposed shielding, which simplifies communication. A further advantage consists in avoiding interferences between identification processes which are carried out on different containers which are, however, located in spatial proximity to one another. A further advantage consists in that the communication is not impaired by spontaneous radio emissions in the surroundings or other external noise sources. Finally, another advantage consists in that unauthorized listening-in to the communication is considerably simplified.

Problems solved by technology

One disadvantage of barcodes is frequently the low memory capacity for information, which also cannot be amended subsequently.

In addition, the readout or readoff (“scanning”) of data is relatively inconvenient and time-consuming (visual contact is required).

In practice, many problems arise with the RFID systems and methods used at the present time, which make it difficult if not impossible to use RFID technology in many areas of application.

A first series of problems relates to the reliability of the technology.

Another range of problems is data security.

In this respect, for example, there is the risk of listening in to the data communication and the risk of spoofing information.

Known RFID systems have so far frequently failed because of the problems described above, particularly for identifying articles located in a container.

In this case of application, data transmission between transponder and reader is impaired, for example, by metal structures of the articles (e.g. tin cans) and also of the container (e.g. metal shopping carts).
