Fare collection refers to the process of gathering payments from passengers using public transportation systems, such as buses, trains, and subways. This system ensures that users contribute to the operational costs of these services. Fare collection can be done through various methods, including cash payments, electronic tickets, and contactless cards. Modern fare collection systems often utilize technology to streamline the process. For example, smart cards allow passengers to load funds and tap their card on a reader for quick access. Additionally, mobile apps enable users to purchase tickets digitally, making fare collection more efficient and user-friendly.
