This is a lead retrieval web app I developed for companies that specialize in trade show technology.
Before each trade show an initial CSV file with all the attendees is imported into the database. During the trade show the vendors use the codeREADr smartphone app to track sales leads. At the end of the show all of those sales leads are uploaded to codeREADr and forwarded to our database. The vendors can then log into a web portal and download all their leads in CSV format. The final CSV download combines data from the initial CSV import and codeREADr.
