An e-fundraizing system includes a mobile device and a server. The mobile device produces, or is configured to respond to, an indicator of one or more specific donation amounts. The mobile device sends a first message to the server in response to the indicator. The mobile device receives a second message in response to the sent first message. The mobile device receives a user input based on the received second message. The mobile device sends a third message to a server in response to the user input. A user of the mobile device donates a specific amount based on the sent third message.
