Bi-Directional Information Exchange with Computing Handheld Devices

The Bi-Directional Information Exchange with Handheld Computing Devicesz\u27 project introduces two new concepts: dynamic digital receipts and personal data warehousing. Dynamic digital receipts means digitalizing paper transactions generated from points of sale. Personal data warehousing means organizing and collecting data for later viewing and analysis. The consumer will be able to use a handheld device such as a cell phone or PDA to receive and store a transaction in XML format. Later on, the user can upload the receipt through a web application to a personal data warehouse for storage or management of receipts. The web interface also allows users to export the receipts to money management software. The digital receipt is transferred from the point of sale to the handheld device using Bluetooth technology. The implementation of the digital receipt concept will allow users to manage their receipts and store them neatly without restrictions on manipulating their own data
