Real Time Decision making
Adaptive Modelling
 Global Profiling

12. Tango's Approach
Could fraud analytics do a better job of protecting not just Anil’s account, but his buying
experience?
Situation : Anil who is living in Kolkata, is on a vacation to J & K.
He is buying a Snow Board from a high-end sporting store.
• Bank A’s Credit Card declined the transaction (Traditional Detection System)
Anil’s Feedback on this : “Being declined was annoying, but not enough to leave
the bank. Still, if they keep bombarding me with irrelevant offers while declining the
purchases I really do want to make, I’m going to think twice about jumping ship.”
• Bank B’s Card approved the transaction (Innovative Streaming Analytics)

13. Tango's Approach – Techniques Incorporated
•Behaviour Sorted Lists – Using Transaction Based Scoring, Behavioural Analytics
capture the granularity of customer habitual patterns.
•Collaborative Profiles - Using Global Profiling, we determine probability based on
the behaviour patterns of other cardholders.
with similar characteristics

14. Tango's Approach – How it works?
• Fraud risk is lower if some aspects of the transaction matches the cardholder
favourites.
• Even with no favourites match, there is a way to anticipate new cardholder’s
behaviour.
• It maps actual individuals to multiple behavioural archetypes in real time and updates
the mapping with each new transaction.
• These archetypes are not conceptual, hand-built categories. Rather, they are machine-
learned by an algorithm that analyzes historical transactional data which can come from
multiple sources in any form.

15. Tango's Approach – How it works?
>>How wide is the difference <<
Actual customer behaviour
is mapped to archetypes in
real time.
The wider the change in
archetype distribution,
the riskier the
transaction.

16. Tango's Approach – How it works?
• As the quantity and variety of data being captured continues to expand, one
of the most important things analytics can do for us is to help us understand
change.
• Knowing ‘what is changing’ and ‘whether it’s important’ is the key in
creating vitality and value in customer relationships, while operating in a lean
and efficient manner.
