Card2Lead™ lead retrieval system for iPhone and iPad is an ideal solution for shows/conferences that do not have a machine readable badge or does not have a badge at all. You can scan a business card of an attendee. Also, it can be used to scan show badges that have limited data on barcode. This is used by firms that want to avoid the high cost of renting the show system while still getting good contact details and notes for each lead to follow-up. It scans using iPhone/iPad camera.
