(Yicai Global) Sept. 6 -- Shared coins are available free of charge at nearly 300 bus stops in Hohhot, the capital of Inner Mongolia, TechWeb reported yesterday.

One site had eight coins worth USD0.15 (CNY1) each with a sign that said, "Only take one coin at a time, and give it back tomorrow."

With the increased popularity of mobile payments, many people do not carry enough small change for purchasing tickets. Coin pools and trays at metro stations and bus stops can help them out.
