Credit Cards may Play a Role in Shaping Country Policy: Study

Purchase patterns analyzed from credit card data can help shape government policy finds a new study. These patterns can help understand the socio-economic status and health status of women and girls in developing countries.

Analysis of credit card usage and mobile data usage can help the government map urban lifestyles and understand human mobility as well as socio-economic status and health status of women and girls in developing countries. The findings of this study are published in the Nature Communications journal.

Credit Card Records (CCRs) are currently used to measure similarities in purchasing activity, but for the first time researchers have used the data along with Call Detailed Records (CDRs) to understand the daily rhythms of human mobility and communication.

Credit Cards, Overdue Household Bills May Increase Depressive Symptoms
The link between short-term debt and depression was strong among unmarried people, people reaching retirement age and those who are less well educated.

‘This kind of research may enable the government policymakers to make more informed decisions about resource allocations, to address socio-economic inequality and economic growth ’

Combining both reveals patterns in citizens' socio-economic behaviors.

For the study, published today in Nature Communications, researchers used anonymous and aggregated credit card data from a major city, with the results allowing them to group the urban population into six clusters.

Older women dominated the 'Homemaker' cluster and tended to have the least expenditure and mobility, with their core transaction being grocery shops. The 'Commuters' cluster was mainly men who lived the farthest from the city center.

New Alarm: E-Pick Pockets Could 'skim' Your Credit Cards for Money
A new breed of scams is about to take flight thanks to technology - it's called e-pick pocketing.

Young people can be split into two groups, with the younger having taxis as their core transaction. The slightly older group also has computer networks and information services, with a higher than average expenditure and operating mainly within the city center.

The research, conducted in collaboration with Grandata and UN Global Pulse, is part of a wider project funded by the United Nations Foundation and the Gates Foundation to investigate the economic, social and health status of women and girls in developing countries.

Follow These Tips to Curb Those Extra Kilos This Christmas Season
With all those carb-heavy boozy party invitations, tempting foods, stress and overworked credit cards, the run-up to New Year's day can really be a tough time.

Lead researcher Dr. Riccardo Di Clemente (UCL Centre for Advance Spatial Analysis), said: "Our approach brings together human mobility behavioral dynamics with socio-economic and demographic information.

"This may enable policymakers to make more informed decisions about resource allocations to address socio-economic inequality, economic growth and improve social cohesion."

Want to Avoid Getting Parking Tickets? Use 'SpotHero' to Book Your Parking Spot
An app to let drivers seamlessly book daily or monthly parking spots using their credit cards and save getting parking tickets was launched by an online parking-reservation firm in NY.

Principal investigator Professor Marta C. Gonzalez (UC Berkeley College of Environmental Design), said: "Mobile phone data is already used for transport planning. Through this research, we found that credit card data can allow us to understand how groups of citizens move and communicate, as well as revealing their spending patterns.

"The method gives us a lot of information from data passively collected worldwide, uncovering purchase sequences of uses by type and their role in their space and social network."

The team found that analyzing CCRs together with CDRs reveals how women cope with stressors such as recessions and macroeconomic policy shifts and could be used when planning systems to enable more women to use mobile money rather than carry cash.

The method and results can be used when designing and managing effective social protection systems in developing countries and could be particularly valuable for urban development, such as planning infrastructure and mapping neighborhoods.
