Mobile ticketing works by allowing users to purchase tickets online and have them delivered as text messages with barcodes to their phones. Users register their mobile number, receive an alphanumeric code by email, and present the ticket barcode at the event by leaving the text message on their phone screen. This mobile ticketing system is convenient as it eliminates the need for printed tickets and has been implemented for various events and transportation through barcode scanners at venues. The technology is seen as promising but will require further development and testing to realize its full potential.
