Automated Fare Collection (AFC) refers to systems that streamline the process of collecting fares in public transportation. These systems use technology such as smart cards, mobile apps, and contactless payment methods to allow passengers to pay for their rides quickly and efficiently. This reduces the need for cash transactions and speeds up boarding times. AFC systems are commonly found in subways, buses, and trains, making travel more convenient for users. By automating fare collection, transit agencies can also improve revenue management and reduce operational costs associated with manual fare collection methods.
