China's mobile payment operators are entering the public transportation sphere with ambitious promotions for their new e-products that promise to change commuters' age-old ways of paying for their city rides, experts said.

Ant Financial, an affiliate of Hangzhou-based tech titan Alibaba, announced last month that its Alipay has entered local bus networks in 50 domestic cities. This service would reach 100 cities this year, including third - and fourth-tier cities.
