Steps in Transaction Processing
The processing of a transaction based on a postal code follows a structured workflow. This workflow is designed for efficiency and security, safeguarding against potential fraud.
- Data Extraction: The system first extracts the postal code from the transaction details.
- Database Lookup: The extracted postal code is then matched against a comprehensive database of valid postal codes, typically a database maintained by the issuing bank or a third-party provider. This step involves checking for the accuracy of the code.
- Validation Rules: The system applies predefined validation rules to confirm the postal code’s structure and format. This involves checking for the presence of specific characters, the correct number of digits, and compliance with regional standards.
- Geographic Location Verification: The system uses the postal code to identify the corresponding geographic location. This helps in determining if the location matches the cardholder’s address or if the transaction is geographically plausible.
- Fraud Detection: The identified location is analyzed against fraud patterns and known risk indicators. This process includes comparing the postal code to historical transaction data and identifying any unusual patterns that might suggest fraudulent activity.
- Authorization: If the postal code validates successfully and no fraud indicators are detected, the transaction proceeds to the authorization phase.
Role of Postal Codes in Fraud Detection
Postal codes play a critical role in detecting fraudulent transactions. They act as a crucial piece of information in the fraud detection process.
- Geographic Profiling: Analyzing transaction patterns based on postal codes helps identify suspicious activities. For instance, a large number of transactions from a single postal code in a short period might raise red flags.
- Address Verification: Comparing the postal code to the cardholder’s address helps ensure that the transaction is legitimate and corresponds to the registered cardholder.
- Risk Assessment: By correlating postal codes with known fraud patterns and risk indicators, the system can assess the risk associated with a particular transaction and take appropriate action.
Examples of Postal Code Usage in Authorization
Postal codes are used in various ways during transaction authorization.
