 17
/ 00 Methods or arrangements for effecting co-operative working between equipments covered by two or more of the preceding main groups, e.g. automatic card files incorporating conveying and reading operations
 

 19
/ 00 Record carriers for use with machines and with at least a part designed to carry digital markings (record carriers adapted for controlling specific machines, see the appropriate subclass for the machine, e.g. B 23 Q, D 03 C, G 10 F, H 04 L; form printing B 41; file cards B 42 F 19/00; record carriers in general G 11)

19
/ 02 • characterised by the selection of materials, e.g. to avoid wear during transport through the machine  

19
/ 04 • characterised by the shape  

19
/ 06 • characterised by the kind of the digital marking, e.g. shape, nature, code  

19
/ 063 • • the carrier being marginally punched or notched, e.g. having elongated slots [5]  

19
/ 067 • • Record carriers with conductive marks, printed circuits or semiconductor circuit elements, e.g. credit or identity cards [5]  

19
/ 07 • • • with integrated circuit chips [5]  

19
/ 073 • • • • Special arrangements for circuits, e.g. for protecting identification code in memory (protection against unauthorised use of computer memory G 06 F 12/14) [5]  

19
/ 077 • • • • Constructional details, e.g. mounting of circuits in the carrier [5]  

19
/ 08 • • using markings of different kinds in the same record carrier, e.g. one marking being sensed by optical and the other by magnetic means  

19
/ 10 • • • at least one kind of marking being used for authentication, e.g. of credit or identity cards (verification of coded identity or credit cards in mechanisms actuated by them G 07 F 7/12) [5]  

19
/ 12 • • • • the marking being sensed by magnetic means [5]  

19
/ 14 • • • • the marking being sensed by radiation [5]

/ 16 • • • • • the marking being a hologram or diffraction grating [5]  

19
/ 18 • • • • Constructional details [5]  
 

 21
/ 00 Information retrieval from punched cards designed for manual use or handling by machine (G 06 K 19/00 takes precedence); Apparatus for handling such cards, e.g. marking or correcting

21
/ 02 • in which coincidence of markings is sensed mechanically, e.g. by needle  

21
/ 04 • in which coincidence of markings is sensed optically, e.g. peek-a-boo system  

21
/ 06 • Apparatus or tools adapted for slotting or otherwise marking information-retrieval cards (tools for perforating in general B 26 F)  

21
/ 08 • Apparatus or tools for correcting punching or slotting errors [2]
