What Happens With Your Personal Shopping Data?
Like it or not, advertisers and businesses want to know about your spending habits so they can target you to buy their products and services. Credit card networks and issuers have enormous databases of purchase and shopping data which they aggregate, package and sell.
|Think twice about what you buy with a credit card if you don't like information about you being sold to advertisers.|
Every purchase you make says something about you. This data are collected and you are grouped with others who have similar interests and spending patterns. Businesses then deliver ads aimed specifically to your group.
For years, "cookies" have been used to gather information about your online behavior to create a personal profile and target ads based on that profile. Access to transaction data from your debit or credit card fills in the gaps with purchases you've made in the offline world.
Your name, Social Security number and bank account are never disclosed to the business or merchant. Customers are represented by numeric codes so individuals remain anonymous.
Through third parties, banks and credit card issuers can partner with retailers to offer you deals based on your purchase history. These offers can appear with your billing statement or pop up when you log into your account. You may get an offer by text or email.
CNN reported that merchants pay banks an average fee of 10% to 15% of the purchase price of a product each time a customer uses a discount generated from the bank's data. The bank takes nearly 25% of that fee and pays the rest to an intermediary that works with banks and merchants such as Cardlytics. So if you buy a $500 item, the merchant pays a fee of up to $75; the bank get about 25% of this, or $18.75.
In their terms and conditions, credit card issuers disclose that they can share personal information about people with outside companies for marketing. Visa has filed patent applications for ways that will use credit card transaction data to target digital ads and personalize other content. Visa's profile generator will include nontransaction data from your address as well as information from social network Web sites, credit bureaus, search engines, insurance claims and even DNA databanks.
