Mobile social commerce combines mobile, commerce, and social networking ecosystems. It allows commercial transactions to happen anytime, anywhere through a user's mobile device, while also supporting social interactions. Key elements include ratings, reviews, shared shopping lists, referrals, recommendations, mobile ticketing, coupons, loyalty programs, payments, location services, information services, and banking. Discovery occurs through social games, quizzes, polls and badges, while purchase can involve friends affiliate networks, coupons, product customization using social content, consumer support in social sites, and recommendation engines.
