Hello! After checking, due to Beijing's segmented fare system and the regulations for using Beijing's public transportation card, each passenger needs to have his/her own card (both when boarding and alighting or when entering and exiting subway stations). To avoid any inconvenience, please make sure that your card has enough balance. Thank you for using and supporting the Beijing Municipal Transportation Card. If you have more questions, you can reach us through our customer service hotline at 010-96066, our official WeChat account "Beijing Municipal Transportation Card" (北京市政交通一卡通), or the "Beijing Yikatong" (北京一卡通) App. Our customer service team will be happy to help you.
