Multi Card Problem Which card do I use when I am at a point of sale to maximize rewards? Choose Randomly ? Build & Solve a complex equation to choose the best ?

Multi-card Problem On average an American card holder has 4 different credit cards (and increasing) On average an American card holder has 4 different credit cards (and increasing) 14% Americans have 6.6 card on average i.e. ~40 million 14% Americans have 6.6 card on average i.e. ~40 million It is good to have multiple cards to have better credit history & higher credit limits. It is good to have multiple cards to have better credit history & higher credit limits. At the same time, the multiplicity of cards should not make it difficult for consumer to shop. At the same time, the multiplicity of cards should not make it difficult for consumer to shop. Different cards offer different rewards on different kind of purchases Different cards offer different rewards on different kind of purchases 60% cards offer some kind of benefits package 60% cards offer some kind of benefits package 23% increase in card holder who use credit cards for the rewards over 5 years 23% increase in card holder who use credit cards for the rewards over 5 years Often it is difficult to remember which card offers benefit on which product Often it is difficult to remember which card offers benefit on which product Foreign transaction fees vary from card to card (lawsuit!) Foreign transaction fees vary from card to card (lawsuit!)

Multi-card Problem How can my cards communicate within themselves and choose the one among them that is best for me for the current transaction ? How can my cards communicate within themselves and choose the one among them that is best for me for the current transaction ? Why has it not been solved ? Why has it not been solved ? Challenge: How do you get these cards to interact with each other to work in the best interest of user? Challenge: How do you get these cards to interact with each other to work in the best interest of user? Business- Since cards are from different banks, they compete instead of co-operating to divide profits instead of sharing. Also issues of credit risk sharing are involved.

Technology- Choosing the best card among the cards a user holds requires knowledge gathering and inference mechanisms using based on hand crafted rules.

MetaCard // Thinks for you. 11925 / Financial Services / Rohit Kumar MetaCard- A multi-card unification mechanism which allows you to register all your (supported) cards to a single MetaCard account. At the time of purchase (online or onsite) you simply use your MetaCard like any other credit card. The MetaCard transaction processing system identifies the best card among the registered cards based on type of purchase, card contract & rewards, account balance, etc.

Demo / Architecture User with multiple cards MetaCard website MetaCard signup Name, Address, etc. List of cards Type (selected from a list), Account info., etc. User Goals (choose from) More return, more miles, better credit rating, etc. MetaCard AI Agent Read and understand contract Read previous statement Construct credit model Construct user model MetaCard Business Expert System Check’s user history Sanity checks Verifications MetaCard Getting a Meta Card

Specific Problem Addressed User does not need to remember credit card contract terms and conditions to make best choice of card for each transaction User does not need to remember credit card contract terms and conditions to make best choice of card for each transaction User experiences confident shopping knowing that he/she made the best choice possible to maximize return (or minimize cost) User experiences confident shopping knowing that he/she made the best choice possible to maximize return (or minimize cost)

Infrastructure The MetaCard system is based largely on existing credit card transaction processing infrastructure. This infrastructure is well established and widely accepted around the globe.

On the transaction processing side, significant computational infrastructure would be required to process 1000s of transaction simultaneously and update user/credit models.

Development Scale: I think a team of less than 10 experts from different areas (like language technologies, machine learning, finance, user interfaces, developers, etc.) can work together and bring up a system in 6 months to an year.
