Abstract: In a quiz game, a first question and a telephone number are displayed at a location. A user enters an answer to the question on an SMS-enabled handset and sends it to the designated telephone number. If the answer is correct, the user receives a further question via SMS, and replies with a further answer. Further questions may be received and answers sent. If all of the answers are correct, the user is prompted to send a message with a name and optionally a choice of prize. The user then receives a voucher number. The voucher number and the name entered by the user, and optionally an identification of the choice of prize, are transmitted to another terminal, which may be another SMS-enabled handset belonging for example to a bartender. The bartender calls out the name and the user presents the voucher number to the bartender. If the presented voucher number matches that received by the bartender, the user receives the prize, such as their choice of free drink.

Abstract: In a customer reward scheme, a user who purchases a product or service is provided with a token code. The user enters a token code in a mobile terminal, which transmits the token code to a server. The server causes a value associated with the token code to be added to the user's account. The user receives a message indicating the total value accumulated in the user's account. If the accumulated value in the user's account exceeds a predetermined threshold, the user receives a message containing a question. The user enters an answer to the question into the terminal. If the answer is correct, a bonus value is added to the customer account. The terminal automatically transmits a prestored terminal or user identity code. This identity code is used as an identifier to create and update the user's account. Messages may be addressed to the user by means of the identity code.

Abstract: A database system is accessible via multiple communications channel types so as to store data entered by users, retrieve the data, and/or to retrieve lists of data according to codes entered by the users. Preferably, the data can be retrieved over wireless channels so that it is available wherever it is needed. In one example, the data comprises a shopping list or list of recipes. Alternatively, the system may be used for collecting or transferring data or performing transactions according to codes transmitted by users over a wireless network. An advantage of this system is that codes may be displayed with advertising material and users may enter codes when they see the advertising material so as to register their interest, obtain more information or conduct a transaction.
