Abstract

An access device includes means for receiving, via a wireless communication link, a key and validity information. The access device also includes wireless communication means for establishing a connection with another party, and for providing the key and validity information to that party. If the key and validity information are determined by the other party to be valid access is provided.

Claims

1. An access device comprising.

means for receiving, via a wireless communication link, a key and validity information,

wireless communication means for establishing a connection with another party, said wireless communication means being arranged to provide said key and said validity information to said another party, wherein if said key and said validity information are determined by the another party to be valid access is provided.

2. A device as claimed in claim 1, wherein said receiving means is arranged to receive additional information relating to the another party

3. A device as claimed in claim 2, wherein said additional information is available to a user of said access device

4. A device as claimed in claim 3, wherein said device comprises a display and said display is arranged to display said additional information.

5. A device as claimed in claim 3, wherein said device comprises a speaker and said speaker is arranged to provide said additional information audibly.

6. A device as claimed in claim 1, wherein said means for receiving said key and validity information comprises a wireless communication means.

7. A device as claimed in claim 6, wherein said wireless communication means for receiving said key and validity information operate at different frequencies to the wireless communication means for establishing a connection

8. A device as claimed in claim 1, wherein said wireless communication means for establishing a connection uses high frequency signals of the order of giga Hertz.

9. A device as claimed in claim 1, wherein said wireless communication means for establishing a connection uses low power signals
