Overview

Alipay+ Code-scanning payment standards are developed by Alipay+ to facilitate interoperability among the following participants:

• User: an individual who has entered into a User Agreement with, and obtains a Payment Product from an MPP.
• MPP (Mobile Payment Provider): an entity in its capacity as a payment service provider where it issues a Mobile Payment Product to a User, enters into a User Agreement with a User, or processes a Transaction for a User.
• Merchant: a natural or legal person that enters into a Transaction with a User, which is acquired by an ACQP.
• ACQP (Acquiring Service Provider): an entity in its capacity as an acquirer or payment processor, including where it enters into a Merchant Agreement with a Merchant, and processes Transactions for its Merchants.

Alipay+ Code-scanning payment standards are applicable to two types of transaction scenarios:

• UPM (User Presented Mode): the User uses a mobile application (for example, a digital wallet provided by an MPP) to present a code image to the Merchant, and the Merchant scans the code image to initiate a Payment.

The code used in this scenario is called Payment Code.

• MPM (Merchant Presented Mode): the Merchant presents a code image to the User, and the User uses a mobile application (for example, a digital wallet provided by an MPP) to scan the code image and initiate a Payment.

The code used in this scenario is called Collection Code.

Alipay+ Code-scanning payment standards are composed of four parts:

• Code format specifications
• Transaction processing guidelines
• User experience design guidelines
• Security guidelines
