What is the purpose of the Chicago Card in fare payment?

The purpose of the Chicago Card in fare payment is primarily to facilitate cashless transactions for users of public transit. This card allows riders to load funds onto it, which can then be used directly to pay for fares when boarding trains or buses, eliminating the need for cash or exact change. This streamlined process enhances convenience for riders, as it speeds up boarding times and simplifies fare management.

While the other options touch on aspects of customer interaction with transit options, they do not encapsulate the central function of the Chicago Card as effectively as the cashless payment feature. Collecting points for rewards, providing discounts for frequent riders, and enabling fare audits may be relevant to different aspects of transit services or programs but do not specifically define the primary purpose of the Chicago Card itself.
