Description

One-time interaction method capable of uniformly executing instructions

Technical Field

The invention relates to an interaction method, in particular to a one-time interaction method capable of uniformly executing instructions, and belongs to the technical field of IC card reading and recording.

Background

In practical application, the IC card needs to process services online in many cases, and at this time, offline data authentication is not needed, and the record indicated by the AFL given by the IC card after the processing option is obtained includes all available application data, including a card issuer public key certificate, an IC card public key certificate, a signature record, and other possible invalid data, which consumes considerable processing time, and has low reading efficiency, a long delay feeling for a client, and poor use experience.

Therefore, there is a need for an improved method for reading and recording interaction of an IC card to solve the above existing problems.

Disclosure of Invention

The invention aims to provide a one-time interaction method capable of uniformly executing instructions.

In order to achieve the purpose, the invention adopts the main technical scheme that:

a one-time interaction method capable of uniformly executing instructions comprises the following steps:

step 1: reading a first IC card by a core through a tag list of required data provided by a service system, and judging each application record as an effective record or an invalid record when the core reads the first IC card;

step 2: after all the data listed in the tag list required by the service system are read out, stopping reading the subsequent records;

and step 3: the new IC card is read out and,

when reading a new IC card, only reading the valid record and not reading the invalid record;

and 4, step 4: after reading all the effective records, the service system finds that the missing tag exists,

at this time, the invalid records must be read really again until no tag is found or all application records are read completely;

and 5: the core re-registers the valid record and the invalid record.

Preferably, in step 1, when the IC card is read for the first time, the valid record list is empty, and this reading of the IC card requires the core to read all application records of the IC card, and determines whether the application record is a valid record or an invalid record.

Preferably, in step 2, in the process of reading the IC card for the first time, it is determined at any time whether all the key tags have been read, and when all the key tags are read, the reading of the application record is immediately stopped, and an effective record table is generated.

Preferably, in step 3, the core first reads the record in the valid record table, if the new IC card AFL does not contain the record in the valid record table, the new IC card AFL does not read, when all the key tags are judged to be read, the reading of the application record of the IC card is terminated, and for the invalid record, the record is directly returned to "\\ x70\ x 00", which indicates that the record has no data.

Preferably, in step 4, after the record indicated by the valid record table is read, if some key tags are lacked, all other unread application records of the AFL label of the new IC card are continuously read, and the valid record table is modified according to the application record condition of the new IC card.

Preferably, the method for reading the application record of the smart IC card only occurs in an APDU interaction layer at the lowest layer of the core.

Preferably, the business system is a bank/non-bank accounting system located away from the IC card machine;

the core is software for executing EMV/PBOC debit and credit standard flow;

the key tag is the tag which is required to be uploaded by the service system.

Preferably, the IC card is the following two types of IC cards:

a: debit cards that conform to the EMV2004 and later releases specifications,

b: debit cards conforming to the PBOC2.0 and later version specifications;

the IC card machine is a device directly interacting with the IC card.

Preferably, the effective record is an application record of the IC card containing the key tag;

invalid records are application records of which the IC card does not contain the key tag;

the active record table is a record list containing active records.

The invention has at least the following beneficial effects: the IC card intelligent reading application records only read partial records, thereby shortening the transaction processing time, improving the reading efficiency and greatly improving the time delay feeling of customers.

Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

As shown in fig. 1, the one-time interaction method capable of uniformly executing instructions provided by this embodiment includes the following steps:

step 1: through the list of the required data tag provided by the service system, the core reads the first IC card,

when the core reads the IC card for the first time, the valid record list is empty, the IC card reading at this time needs the core to read all application records of the IC card, and the application records are judged to be valid records or invalid records;

step 2: in the process of reading the IC card for the first time, judging whether all the key tags are read at any time, and immediately stopping reading the application records continuously when all the key tags are read out, and generating an effective record table;

and step 3: the new IC card is read out and,

the core firstly reads the record in the effective record table, if the new IC card AFL does not contain the record in the effective record table, the record is not read, when all the key tags are judged to be read out, the reading of the IC card application record is stopped, and for the invalid record, the record is directly returned to \ x70\ x 00', so that the record is marked to have no data;

and 4, step 4: after reading all the effective records, the service system finds that the missing tag exists,

at the moment, the invalid records must be read really, after the records marked by the valid record table are read, some key tags are lacked, all other unread application records marked by the AFL of the new IC card are read continuously, the valid record table is corrected according to the application record condition of the new IC card, and no tag is missed or all application records are read completely when finding out;

and 5: the core re-registers the valid record and the invalid record.

The IC card intelligent reading application records only read partial records, thereby shortening the transaction processing time, improving the reading efficiency and greatly improving the time delay feeling of customers.

In the embodiment, the method for reading the application record of the intelligent IC card only occurs in the APDU interaction layer at the bottommost layer of the core, and the whole core framework is not influenced completely;

the business system is a bank/non-bank accounting system which is far away from the IC card machine;

the core is software for executing EMV/PBOC debit and credit standard flow;

the key tag is a tag which is required to be uploaded by a service system;

the C card is the following two types of IC cards:

a: debit cards that conform to the EMV2004 and later releases specifications,

b: debit cards conforming to the PBOC2.0 and later version specifications;

the IC card machine is a device directly interacting with the IC card;

the effective record is an application record of the IC card containing the key tag;

invalid records are application records of which the IC card does not contain the key tag;

the active record table is a record list containing active records.

In this embodiment, it is assumed that the service system needs to send the following tag to the core when performing online transaction:

5A 5F24 9F26 9F27 9F10 9F37 9F36 95 9A 9C 9F02 82 9F34 9F41 9F0B 5F20

removing the tag which is not read in the IC card application record, and the rest tag:

5A: a card number;

5F 24: an expiration date;

5F 20: the name of the cardholder;

9F 0B: card holder name extension;

adding tag which must exist in the application record of the IC card:

8C：CDOL1；

8D：CDOL2；

in a bank IC card structure, the application records total 792 bytes,
