A Transportation Card is a smart card used for convenient travel on public transport systems, such as buses, trains, and subways. It allows users to load money or travel passes onto the card, which can then be tapped or scanned at entry and exit points. This system simplifies fare payment and reduces the need for cash or paper tickets. Many cities offer their own versions of the Transportation Card, often linked to specific transit networks. Examples include the Oyster Card in London and the MetroCard in New York City. These cards can also provide discounts and special offers for frequent travelers.
