Title:
METHOD AND DEVICE FACILITATING EXPANSION OF PRIMARY PAYMENT INSTRUMENTS
Document Type and Number:
WIPO Patent Application WO/2018/001120
Kind Code:
A1
Abstract:
Provided are a method and device facilitating expansion of primary payment instruments. The method comprises: determining a type of a primary payment instrument (S101); searching for a primary key generation rule corresponding to the type (S102); and generating, according to the primary key generation rule, a payment primary key for the primary payment instrument, and storing a correspondence relationship between the primary payment instrument and the payment primary key thereof (S103), wherein the primary key generation rule specifies a primary payment instrument element for generating the payment primary key, and primary payment instrument elements for generating payment primary keys specified in primary key generation rules corresponding to different types of primary payment instruments are different. In the above payment primary key generation method, a payment primary key can be generated for a primary payment instrument according to a primary key generation rule corresponding to a type of the primary payment instrument. Upon expansion of primary payment instruments, e.g. addition of a new type of primary payment instruments, or addition of a new primary payment instrument element for a primary payment instrument, it only requires an update to the primary key generation rule without needing to develop a complete new model, thereby significantly reducing development costs.
