Aggregated

This type of transaction uses a contactless terminal at points of access to the transit service. The final fare charged is not always known at the time of travel. Each fare is calculated at the end of a trip. The fares are then aggregated together and charged to the customer at the end of a travel period or when the aggregated fare limit is breaches.
The travel period is also called as Maximal Travel Time (MTT) which should not exceed beyond 14 days. The aggregated total fare limit is called as Cumulative Spend Limit (CSL). The Cumulative Spend Limit (CSL) is decided by the merchant.
