The Shenzhen Tong is a reusable contactless stored value smartcard used for electronic payments in public transportation and some other areas in Shenzhen city, Guangdong Province, People's Republic of China. It was developed by Shenzhen Modern Computer, the provider of automatic fare collection systems to Shenzhen Metro, with cooperation from Octopus Cards Limited, the operator of Hong Kong's Octopus cards system. It was first adopted by minibuses in Shenzhen, until the new system was introduced by Shenzhen Metro. The English name was originally TransCard.
