Terminal Data Capability

final Data Capability What is it? Generally, It is a data element that stores information particularly on destruction that can be individually addressed by tag ID. Data element resident in the terminal shall be under control of one of the following parties last(a) manufacturer For example, IFD Serial Number Acquirer/Agent For example, Merchant Category Code Merchant For example, Local Date and Local Time (these may be controlled by either merchant or acquirer) rod should be constructed in such a way that data which is under control of acquirer is only initialised and updated by the acquirer (or its agent).Types 1. operation Independent1 Data Terminal related data Transaction related data -Unique to terminal. -Shall have parameters initialised so that it can identify what language(s) supported to offshoot the carte du jours language preference.2. finish Dependent2 Data Characteristic A terminal data shall be initialized in the terminal or obtainable at the sentence of a tran saction. A terminal data can be of any format alphabetic, numeric to binary. Some terminal data serves as a unvarying whereas the rest is updatable. Each terminal data has its own functionality and usage which facilitates an EMV transaction. The dependency of the terminal data in application indicates how data management is done in terminal. During the transaction, the terminal shall ignore any data object coming from the ICC which is terminal-sourced or issuer-sourced. How it involved in EMV Transaction (Exchange/Supply Data to ICC) take Record (updatable) ComparableReference Notes Terminal data element, ICC data element, Issuer data element, EMV function. Counter Record Cardholder bank check Method (CVM) Results Being stria/updated upon Cardholder Verification completion. P102B3 Consists of 3 bytes CVM Performed, CVM Condition, and CVM Result. There are 5 applicable CVMs in Cardholder Verification Online PIN, Offline PIN, Signature, No CMV Required, and Combo CVM (2 CVM combination). After a successful CVM, CVM Results reflect the successful CVM an unsuccessful CVM, CVM Results reflect the unsuccessful CVM. Byte 3 of CVM Results is set to successful, IFF i. applicable CVM is No CVM call for, and terminal supports it. ii. Offline PIN verification by the ICC is successful. Byte 3 of CVM Results is set to unknown, IFF i. Applicable CVM is Signature, and terminal supports it. ii. Online PIN verification is successful. Byte 3 of CVM Results is set to failed, IFF i. Previous applicable CVM is failed, and succeeding (last) application CVM failed as well. Byte 1 and byte 2 of CVM Results indicate method and condition of the last performed CVM throughout CMV List.In addition, byte 2 is set to 00 (No meaning) IFF byte 1 is 3F (No CVM performed). Table 2 shows all the possible failed/unknown CVM Results.

Diagram P165B4, TVR bytes breakdown TVR byte EMV Function Status jotted on bits When will it be set RFU Reserved for future use 1 Offline Data Authentication RFU CDA failed If CDA is performed provided unsuccessful. P44B4 DDA failed If DDA is performed but unsuccessful. Card appears on terminal exception (set at Terminal Risk If a match on presence card (Application PAN and Application PAN wariness) Sequence Number) is found in the exception file. ICC data missing (Can be set at any function) When an optional data object that is required because of the existence of other data objects or that is required to support functions that must be performed (AIP) is missing. SDA failed If SDA is performed but unsuccessful. Off line Data Authentication was not performed If neither SDA nor DDA nor CDA is performed. RFU Reserved for future use 2 Processing Restriction RFU RFU New Card (set at Terminal Risk Management) If utmost Online ATC Register == 0. P113B3 Requested service not quited for card product If all test against Issuer Country Code and Terminal Country Code fail. T32B4 Application not yet effective If Transaction Date Application Effective Date Expired application If Transaction Date Application Expiration Date ICC and terminal have different application versions If AVN in ICC ? AVN in Terminal. RFU Reserved for future use 3 Cardholder Verification RFU Online PIN entered If online PIN is successfully entered. PIN entry required, PIN pad present, but PIN was not entered If CVM is online/offline PIN, but bypassed by terminal in the direction of merchant or cardholder. PIN entry required and PIN pad not present or not worki ng If CVM is online/offline PIN, but neither of them were supported by terminal or malfunctioned PIN pad. PIN Try assign exceeded If PIN Try Counter 1. Unrecognised CVM If CVM is not recognized by terminal. Cardholder Verification was not successful If CVM List is exhausted without any successful case or applicable CVM indicates live CVM Processing. RFU Reserved for future use 4 Terminal Risk Management RFU RFU Merchant forced transaction online An attended terminal may allow an attendant to force a transaction online, such as in a situation where the attendant is suspicious of the cardholder. If this function is performed, it should occur at the get of the transaction. Transaction selected randomly for Online Processing Upper Consecutive Offline Limit exceeded If ATC ? Last Online ATC Register (Precautious) or If (ATC Last Online ATC Register) Upper Consecutive Offline Limit. P113B3 Lower Consecutive Of fline Limit exceeded If ATC ?Last Online ATC Register (Precautious) or If (ATC Last Online ATC Register) Lower Consecutive Offline Limit. P113B3 Transaction exceeds floor limit If (Amount, Authorize + Amount stored in log) Terminal Floor Limit. Or if (Amount, Authorize) appropriate Terminal Floor Limit. P111B3 RFU Reserved for future use 5 RFU RFU RFU Script Processing Script Processing failed after final GENERATE AC If an error occurred while ICC touch Issuer Script Template 1. Script Processing failed before final GENERATE AC If an error occurred while ICC processing Issuer Script Template 2. Online Processing Issuer authentication failed When Issuer Authentication Data (part of authorisation response message) from Issuer sent to ICC via EXTERNAL AUTHENTICATE/ second GENERATE AC command failed, i. e. (SW1 SW2) = 9090. P120B3 thoughtlessness TDOL used If TDOL in ICC not presented and Default TDOL in terminal i s used to generate TC Hash Value.

AVN in Terminal. Comparable Reference Array What is it? In data storage, an array is a method for storing information on multiple devices. In general, an array is a number of items arranged in some specified way for example, in a list of in a three-dimensional table.In reckoner programming languages, an array is a group of objects with the same attributes that can be addressed individually, using such techniques as subscripting. An array is a collection of sympathetic elements, must have the same data type. In random access memory (RAM), an array is the arrangement of memory cells. Characteristic You need an index to grade their value. The index starts fr om 0 and end with the length 1. Data in array must be in same data type. What is its implementation? List, queue, stack, link list. 1 No matter what application is selected, its data will not be affected. 2 If an application changed, its value changed as well.
