Appalicability
Merchant side: Acquirers should have already obtained the POS acquiring license and support POS business.
Transit terminals should be certified on L2 & L3.
Scenarios
Public transit systems, such as buses, metros, ferries, BRT, etc.
Payment Flow
Single Fare Mode:
Step 1: The cardholder taps their card upon entry into the station. The transit terminal performs a series of offline checks, and if all the checks are successful, the cardholder will be allowed to travel.
Step 2: The trip info is uploaded to the transit backend system.
Step 3-5: The transit backend system / acquirer submits a purchase / fixed-amount authorization request through UnionPay to the issuer.
Step 6-9: The issuer returns an authorization response. In the event of a decline response, the cardholder is added to the deny list.
Aggregated Fare Mode:
Step 1: The cardholder taps their card upon entry into the station. The transit terminal performs a series of offline checks, and if all the checks are successful, the cardholder will be allowed to travel.
Step 2: The trip info is uploaded to the transit backend system.
Step 3-5: In the event of no active pre-auth in the system, the transit backend system / acquirer submits a pre-auth / estimated-amount authorization request through UnionPay to the issuer.
Step 6-9: The issuer returns an authorization response. In the event of a decline response, the cardholder is added to the deny list.
Step 1: The cardholder taps their card upon entry into the station. The transit terminal performs a series of offline checks, and if all the checks are successful, the cardholder will be allowed to travel.
Step 2: The trip info is uploaded to the transit backend system.
