The invention relates to a system for executing system functions, which system contains at least the means mentioned below, that is to say, a contact-bound characteristics block-processing stage that is designed to process a contact-bound characteristics block transferable from a contact-bound data carrier to a contact-bound read-write device and as a consequence of the processing of the contact-bound characteristics block is designed to produce at least one control signal.
The invention relates furthermore to a method of generating a contact-bound characteristics block.
A system corresponding to the construction referred to above in the first paragraph is known, namely in the form of a personal computer system. The known system comprises a personal computer, which is equipped with a read-write device that conforms to the standard ISO 7816. The read-write device is thus of contact-bound construction and is constructed to co-operate with a contact-bound data carrier, namely with a contact-bound card, which contact-bound card likewise complies with the standard ISO 7816. The contact-bound read-write device comprises a contact-bound characteristics block-recognition stage, which is provided and designed to recognize a contact-bound characteristics block transferred from the contact-bound card to the contact-bound read-write device. The contact-bound characteristics block is the characteristics block defined in accordance with the standard ISO 7816, which bears the designation “Answer to Reset” and for which the abbreviation ATR is established and customary. The contact-bound characteristics block ATR is used in the initialization of cards according to ISO 7816 to identify the relevant card, wherein by means of the contact-bound characteristics block ATR inter alia the type of the relevant card and/or the capabilities of the relevant card and/or the manufacturer of the relevant card and/or the distributor of the relevant card and suchlike are communicated to the read-write device. The communicated contact-bound characteristics block is processed by means of the contact-bound characteristics block-processing stage, wherein as a consequence of processing the contact-bound characteristics block ATR a plurality of control signals with or control commands are generated that are utilized to control various portions or regions of the known system. For example, a control signal for enabling the known system is generated. By means of other generated control signals, an automatic activation of various system functions of the known system is performed.
The known system has the limitation that the above-mentioned control signals or control commands can be generated only by means of a contact-bound data carrier and a read-write device provided and constructed for co-operating with contact-bound data carriers. It is therefore always necessary to bring a contact-bound data carrier into contact connection with the contact-bound read-write device, which relatively often requires an inconvenient and consequently not especially desirable operation.
It is an object of the invention to eliminate the above-mentioned problems and to produce an improved system corresponding to the construction mentioned in the introduction in the first paragraph. It is a further object of the invention to produce a new method of creating a contact-bound characteristics block.
To achieve the above-mentioned object, in a system according to the invention features according to the invention are provided so that a system according to the invention can be characterized in the manner specified below, namely:
A system for executing system functions, which system contains at least the means mentioned below, namely a contact-bound characteristics block-processing stage, which is designed to process a contact-bound characteristics block transferable from a contact-bound data carrier to a contact-bound read-write station and which, as a consequence of the processing of the contact-bound characteristics block, is designed to generate at least one control signal, and a contactless read-write device, which is designed to co-operate with a contactless data carrier and which contains a contactless characteristics block-recognition stage, which is designed to recognize a contactless characteristics block transferred from the contactless data carrier to the contactless read-write device, and a contact-bound characteristics block-generation stage, which is designed to process the contactless characteristics block recognized with the contactless characteristics block-recognition stage and which, as a consequence of the processing of the contactless characteristics block, is designed to generate the contact-bound characteristics block, which contact-bound characteristics block, which was generated by processing the contactless characteristics block, can be fed to the contact-bound characteristics block-processing stage.
To achieve the above-mentioned object, in a system according to the invention features according to the invention are provided so that a method according to the invention can be characterized in the manner specified below, namely:
A method of generating a contact-bound characteristics block, which method contains the method steps mentioned below, namely, feeding a contactless characteristics block to a contactless characteristics block-recognition stage and recognizing the contactless characteristics block with the contactless characteristics block-recognition stage and feeding the recognized contactless characteristics block to a contact-bound characteristics block-generation stage and processing the fed contactless characteristics block with the contact-bound characteristics block-generation stage and generating the contact-bound characteristics block with the contact-bound characteristics block-generation stage as a consequence of the processing of the contactless characteristics block with the contact-bound characteristics block-generation stage.
By providing the features according to the invention, in a simple manner and with only modest additional expense, in a system according to the invention it is possible to generate control signals or control commands for the signal-processing circuit of the system according to the invention by means of a contactless data carrier and a contactless read-write device co-operating with the contactless data carrier. By this means the generation of the control signals or control commands is activatable in a substantially more convenient and more expedient manner.

Thus, also in a system according to the invention the control of the signal-processing circuit can be effected by means of the control signals or control commands in exactly the same way as is known from the known existing system, because generation of the control signals or control functions is effected also in the system according to the invention on the basis of the contact-bound characteristics block, which was generated here by utilizing and processing the contactless characteristics block.

This ensures the advantage that the generation of control signals or control commands for the signal-processing circuit of the system according to the invention is activatable both by means of a contactless data carrier and by means of a contact-bound data carrier.
