It is highly recommended to obtain a Shenzhentong card for public transport in Shenzhen. 

The Shenzhen equivalent of Hong Kong's Octopus card, the Shenzhentong card is a contactless prepaid card that is simple to use on the Metro and on most buses in the city. The physical Shenzhentong card is available for sale at most Metro stations, some grocery stores, as well as Shenzhentong outlets, where users can also top up the cards.

You can get access to your digital Shenzhentong card through the WeChat mini-program on your mobile photo. It is also possible to use a Huawei phone as a physical Shenzhentong. Huawei phones have NFC, or near field communication, which allows direct charges from your WeChat or a connected bank account.

Shenzhentong cardholders are eligible for discounts of up to 35% on public buses and a 5% discount on Metro.

A physical Shenzhentong card costs 20 yuan, which is refundable when it is returned. The card can be returned at its customer service sites at Laojie Station, Convention & Exhibition Center Station and Bao’an Center Station.
