Dive Deeper into Consumer's Spending Behavior using Visa Cardholder Transaction Score API

Joko and Doni earn Rp 25 million a month. Both spend Rp 15 million per month. Based on this set of information, you may conclude that Joko and Doni's creditworthiness is similar.


 

But what if we dive deeper into Joko and Doni's spending? Joko has a stable spending pattern and tends to spend on groceries, rent and food. In the last year, he always paid his credit card bills on time and his card has never been declined as he spends within the credit limit. On the other hand, Doni’s spending habits differ from month to month – with the proportion of money spent in different categories varying significantly. In addition, Doni often fails to pay his credit card bills on time and had his card declined multiple times in the last year as he went over his credit limit. Having insight into their spending and payment behaviour can help to better differentiate between the creditworthiness of the two men.


 

At Brick, we believe that such insights would be useful for lender clients in the financial services sector. We have therefore partnered with Visa to allow our clients to utilise our APIs to retrieve such insights from Visa (which are based on the data from Visa debit and credit card transactions) with the consent of the individual cardholders.


 

These insights are provided in the form of the Visa Cardholder Transaction Score & Aggregated Spend Attributes. How can lenders leverage these insights?


  • Improve approval rates by better differentiating between high risk and low risk borrowers
  • Identify existing borrowers who may be eligible for a higher credit line
  • Reduce non-performing loans by identifying riskier borrowers


 

How does the Visa Cardholder Transaction Score API work?


  1. Lender obtains consent from cardholder, as part of that cardholder’s credit application, to authorize retrieval of applicant’s Cardholder Transaction Score and related aggregated spend attributes
  2. Lender calls Brick API to request that applicant’s Cardholder Transaction Score and aggregated spend attributes
  3. Lender receives API response containing the requested data – Cardholder Transaction Score and aggregated spend attributes for the applicant
  4. Lender leverages data to make credit underwriting decision on whether to approve or reject the applicant’s credit application (and related credit limits).
