RFID ionosphere

1. A method comprising:

receiving a composite file on a hand-held device, wherein the composite file comprises a radio frequency identification (RFID) number and a data file;

identifying, by the hand-held device, a user selection of a purchase request associated with the data file, wherein the data file comprises a description of the purchase request; and

transmitting the composite file from the hand-held device to a vendor associated with the purchase request.

2. The method of claim 1 , further comprising:

receiving a response on the hand-held device indicating that the purchase request was received by the vendor, wherein the response comprises the composite file and a confirmation of receipt of the purchase request.

3. The method of claim 2 , wherein the confirmation of receipt comprises a stock keeping unit (SKU) associated with the RFID number.

4. The method of claim 2 , further comprising:

transmitting the response from the hand-held device to a point of sale device; and

receiving at the hand-held device payment information associated with the purchase request.

5. The method of claim 4 , wherein the payment information comprises confirmation of payment sent to the vendor.

6. The method of claim 1 , wherein the composite file is received by the hand-held device from a remote registry server.

7. The method of claim 6 , wherein the composite file is included in a library of items available for purchase from the vendor, and wherein the library of items is received by the hand-held device.

8. A hand-held apparatus comprising:

means for receiving a library of items available for purchase, wherein each of the items is associated with a data file;

means for identifying a user selection of one of the items; and

means for wirelessly transmitting a composite file to a vendor of the items, wherein the composite file comprises a radio frequency identification (RFID) number associated with the one item and the data file, and wherein the data file comprises a description of the one item.

9. The hand-held apparatus of claim 8 , further comprising:

means for combining the RFID number with the data file prior to transmitting the composite file.

10. The hand-held apparatus of claim 8 , wherein the library of items comprises a unique RFID number associated with each of the items.

11. The hand-held apparatus of claim 10 , further comprising:

means for comparing the RFID number with the library of items to identify the unique RFID number associated with the one item.

12. The hand-held apparatus of claim 8 , further comprising:

means for reading the RFID number from a RFID tag; and

means for displaying the description of the one item.

13. The hand-held apparatus of claim 8 , further comprising:

means for receiving confirmation of receipt of the composite file from the vendor, wherein the confirmation of receipt comprises the composite file and payment information.

14. The hand-held apparatus of claim 13 , further comprising:

means for wirelessly transmitting the confirmation of receipt to a point of sales device.

15. A memory device having instructions stored thereon that, in response to execution by a processing device, cause the processing device to perform operations comprising:

receiving, at the processing device, a library of items available for purchase, wherein each of the items is associated with a data file;

identifying a user selection of one of the items; and

wirelessly transmitting a composite file from the processing device to a vendor of the items, wherein the composite file comprises a radio frequency identification (RFID) number associated with the one item and the data file, and wherein the data file comprises a description of the one item.

16. The memory device of claim 15 , wherein the operations further comprise:

querying the vendor with at least a portion of the composite file to determine an availability of the one item.

17. The memory device of claim 15 , wherein the RFID number and the description are combined by the vendor.

18. The memory device of claim 15 , wherein the library of items comprises descriptions of the items, and wherein each of the items is associated with a unique RFID number.

19. The memory device of claim 18 , wherein the operations further comprise:

comparing the RFID number with the library of items to identify the unique RFID number associated with the one item.

20. The memory device of claim 15 , wherein the operations further comprise:

combining the RFID number and the description at the processing device.
