    Visa Mobility and Transport Transaction
    These are the key characteristics of the Visa Mobility and Transport Transaction (MTT) model: 
            
- Journeys are multimodal.
 - Fares are based on distance.
 - Points of entry are contactless.
 - Accounts are verified with an account verification request (AVR) authorization for a nominal amount or the maximum fare amount.
 - The deny list is checked so that cardholders with previously declined transactions can be blocked.
 - Data can be authenticated offline to confirm the card is valid.
 - Token Management Service(TMS) option for managing sensitive authentication data (SAD).
 - Multiple card taps can be aggregated into a single payment.
 - The back office manages the deny list and distributes them to terminals.
 - The back office records all trips and fares to perform journey reconstruction to calculate the final fare.
 - Standard follow-on payment services can be used to capture, reverse, or void transactions.
 - First ride risk protection when the first authorization fails.
 - When the AVR authorization is declined, debt recovery can be performed
