An app to scan qrcodes on conference badges from attendees. When potential customers (leads) approach your booth you can scan their badge and get the provided information as name, company, e-mail address. In case the person qualifies as a so called marketing qualified lead (MQL) you can check the checkbox. For each scanned qrcode one can add additional notes either by typing or by speaking to the app.
When done with all scans one can send a mail (requires Apple Mail) with an attachment that contains all scanned contacts in CSV (comma separated values) format. This file can then imported in a spreadsheet e.g. Numbers or Excel.
