Abstract

A system and method for reading a credential for an access system is provided. The system may include a plurality of readers, link coupling assemblies and a read head housing a plurality of credential pickup coils of the link coupling assemblies. When a user places a credential, the plurality of readers, via link coupling, determines whether the credential utilizes the same modulation technology, and the reader which utilizes the same modulation technology reads the credential, thereafter determining whether or not to grant the user access.

Claims

1. A credential scanning system comprising:

a read head housing a first credential pickup coil and a second credential pickup coil;

a first transmission line connecting a first reader pickup coil to said first credential pickup coil;

a second transmission line connecting a second reader pickup coil to said second credential pickup coil;

a first reader within wireless transmission range of said first reader pickup coil, said first reader being electromagnetically isolated from said read head; and

a second reader within wireless transmission range of said second reader pickup coil;

wherein said first reader is electromagnetically isolated from said second reader;

wherein upon having a first credential presented to said read head, said first credential pickup coil interrogates said first credential and transmits said first credential to said first reader pickup coil, and said first reader is arranged to interrogate said first credential; and

wherein upon having a second credential presented to said read head, said second credential pickup coil interrogates said first credential and transmits said second credential to said second reader pickup coil, and said second reader is arranged to interrogate said second credential.

2. The system of claim 1, wherein said first reader pickup coil is permanently physically positioned proximate said first reader within wireless transmission range thereof.

3. The system of claim 1, wherein said first reader is physically isolated from said second reader.

4. The system of claim 1, further comprising a shielding divider between said first reader and said second reader.

5. The system of claim 1, wherein said first reader is physically isolated from said read head.

6. The system of claim 1, wherein said first reader is located in a secured room and said read head is located in an area external to said secured room.

7. The system of claim 1, further comprising a first access control panel connected to said first reader.

8. The system of claim 1, further comprising a power source between said first reader pickup coil and said second reader pickup coil.

9. The system of claim 1, further comprising an indicator between said first credential pickup coil and said second credential pickup coil.

10. The system of claim 1, further comprising a power source and a first blocking capacitor connected to said first reader pickup coil and an indicator and second blocking capacitor connected to said first credential pickup coil.

11. The system of claim 1, wherein said first reader utilizes a first modulation technology and said second reader utilizes a second modulation technology different from said first modulation technology.

12. The system of claim 1, wherein said first credential pickup coil operates on a first frequency and said second credential pickup coil operates on a second frequency different from said first frequency.

13. A credential scanning system comprising:

a read head housing a first credential pickup coil and a second credential pickup coil;

a first transmission line connecting a first reader pickup coil to said first credential pickup coil;

a second transmission line connecting a second reader pickup coil to said second credential pickup coil;

a first reader within wireless transmission range of said first reader pickup coil, said first reader utilizing a first modulation technology, said first reader being electromagnetically isolated from said read head; and

a second reader within wireless transmission range of said second reader pickup coil, said second reader utilizing a second modulation technology different from said first modulation technology;

wherein said first reader is electromagnetically isolated from said second reader;

wherein said first reader interrogates a first credential utilizing a credential modulation technology when said first credential is within range of said first credential pickup coil, and said second reader interrogates said first credential when said first credential is within range of said second credential pickup coil;

wherein said first credential pickup coil is arranged to transmit said credential to said first reader pickup coil if said credential modulation technology is equivalent to said first modulation technology, said first reader reads said credential, and

wherein said second credential pickup coil is arranged to transmit said credential to said second reader pickup coil if said credential modulation technology is equivalent to said second modulation technology, and said second reader reads said first credential.

14. The system of claim 13, wherein said first reader is physically isolated from said second reader.

15. The system of claim 13, further comprising a shielding divider between said first reader and said second reader.

16. The system of claim 13, wherein said first reader is physically isolated from said read head.

17. The system of claim 13, wherein said first reader is located in a secured room and said read head is located in an area external to said secured room.

18. The system of claim 13, further comprising a first access control panel connected to said first reader.

19. The system of claim 13, further comprising a power source between said first reader pickup coil and said second reader pickup coil.

20. The system of claim 13, further comprising an indicator between said first credential pickup coil and said second credential pickup coil.

21. The system of claim 13, further comprising a power source and a first blocking capacitor connected to said first reader pickup coil and an indicator and second blocking capacitor connected to said first credential pickup coil.

22. The system of claim 13, wherein said first credential pickup coil operates on a first frequency and said second credential pickup coil operates on a second frequency different from said first frequency.

23. A method for reading a credential to determine whether or not to grant access requested by a user, said method comprising:

providing a first credential coil and a first reader pickup coil connected by a first transmission line;

providing a second credential coil and a second reader pickup coil connected by a second transmission line;

providing a read head housing said first credential coil and said second credential coil;

providing a first reader utilizing a first modulation technology, said first reader being in wireless communication with said first reader pickup coil, wherein said first reader is electromagnetically isolated from said read head;

providing a second reader utilizing a second modulation technology different from said first modulation technology, said second reader being in wireless communication with said second reader pickup coil, wherein said second reader is electromagnetically isolated from said first reader;

interrogating a credential with said first reader when said credential is within readable range of a first credential coil;

interrogating said credential with said second reader when said credential is within readable range of a second credential coil;

determining if said credential utilizes said first modulation technology;

determining if said credential utilizes said second modulation technology; and

if said credential utilizes said first modulation technology, transmitting said credential from said first credential coil to said first reader pickup coil and reading said credential with said first reader, and if said credential utilizes said second modulation technology, transmitting said credential from said second credential coil to said second reader pickup coil and reading said credential with said second reader.

24. The method of claim 23, further comprising transmitting a credential data of said credential to a first access control panel connected to said first reader and determining whether or not to grant access.

25. The method of claim 23, further comprising maintaining said first reader physically isolated from said second reader.

26. The method of claim 23, further comprising indicating whether or not access is granted.

27. The method of claim 23, further comprising transmitting data in differential mode and transferring power in common mode.

28. The method of claim 23, further comprising displaying a message on a display unit.
