PCT No. PCT/DE97/00485 Sec. 371 Date Jan. 27, 1999 Sec. 102(e) Date Jan. 27, 1999 PCT Filed Mar. 12, 1997 PCT Pub. No. WO97/35398 PCT Pub. Date Sep. 25, 1997A process for data communications whereby an acquisition device is used to gather information data through a transmitter-user, these data then being provided with appropriate address data and made available to an authorized receiver-user in a host computer for issuing the same. A data communications system comprising a transportable data carrier, a data acquisition device for collecting and storing data on the data carrier, a data read-out device for reading the data carrier and a data output device. During a configuration operation preceding data communication, a transportable data carrier is provided with data carrier-specific and/or user-specific identification data. The transportable data carrier is used at least by the receiver-user in such a way that these identification data are read out from the data carrier to determine authorization. Where there is agreement, at least one reception signal is issued to the receiver-user to characterize available information data. A number of spatially separated communications devices are provided and contain at least the data read device and the data output device. These communications devices are provided with a link, via a leased line, selectable telephone line or radio data line, to a host computer. Non-alterable data carrier-specific identifying data are stored on said data carrier. User-specific identification data and input-capable receiver-specific address data and information data can be stored via the data acquisition device. |
