Mobile commerce was first introduced in 1997 when two Coca Cola vending machines in Finland enabled purchases via mobile phones. Since then, m-commerce has grown to include services like mobile ticketing, money transfers, content purchases, information services, banking, browsing, and marketing via mobile devices like phones, PDAs, and smartphones. Some key applications include airline, cinema, and railway ticketing as well as mobile banking services. Location-based services are also an important part of m-commerce, allowing merchants to provide local deals and offers to customers based on their location.
