Abstract: A shopping assistant method and system provides a consumer with a mobile terminal in a shopping mall as a shopping assistant. The consumer can input a shopping list to the mobile terminal in advance and login at an entrance of the shopping mall in a wireless way for sending the shopping list to a remote server in the shopping mall. The remote server finds goods in the shopping list from its database that have identical names and other goods having information that meets with a pre-stored preference condition, and then sends the information found to the mobile terminal for display. Accordingly, the consumer can conveniently compare prices among numerous goods and quickly get the desired goods, or the closest ones. When the consumer finishes shopping, the remote server further deducts the amount from a personal financial account so as to complete an e-commerce.
