9. A method as claimed in claim 7 or claim 8, comprising receiving a request from the client device to send a communication to the user, the communication being directed to a user identifier data item identified in response to the identifier search query and comprising at least some of the set of data items relating to the user interaction

10. A method as claimed in any preceding claim, wherein in the event the search results comprise multiple candidate user identifier data items, the method comprises receiving partial data relating to the user identifier data item from a client device and using the partial data to filter the candidate user identifier data items to form a filtered set of user identifier data items.

11. A method as claimed in claim 10, the method comprising outputting the filtered set when the number of candidate user identifier data items in the filtered set meets a predetermined threshold.

12. A method as claimed in claim 11, wherein the predetermined threshold equals a single user identifier data item.

13. A method as claimed in any preceding claim, comprising storing the set of data items as a new data record within the first data store.

14. A method as claimed in claim 13, comprising adding a user identifier data item to the new data record once the user identifier data item has been confirmed by the user.

15. A method as claimed in any preceding claim, wherein the received set of data items comprises a plurality of identifier proxy data items.

16. A method as claimed in claim 15, comprising formulating the identifier search query using a subset of the plurality of identifier proxy data items.

17. A method as claimed in claim 15, comprising formulating the identifier search query using the plurality of identifier proxy data items.

18. A method as claimed in any preceding claim, comprising analysing the plurality of data items to determine the identifier proxy data category most frequently associated with a user identifier data item.

19. A method as claimed in any preceding claim, wherein the user interaction comprises a transaction at a point of sale system.

20. A method as claimed in any preceding claim, wherein the first data store comprises historic transaction data.

21. A method as claimed in any preceding claim, wherein the second data store comprises transaction data relating to a current transaction.

22. A method as claimed in any preceding claim, wherein the user identifier data item comprises an email address for the user.

23. A method as claimed in any preceding claim, wherein the identifier proxy data item comprises one or more selected from:

a primary account number of a transaction card belonging to the user;

a masked primary account number of a transaction card belonging to the user;

a loyalty card number of a loyalty card belonging to the user.

24. A method as claimed in any preceding claim, wherein the computing device comprises a server.
