In this guide, we'll explain some of the ways that retailers track shoppers, and how you can protect yourself from such tracking. We'll examine situations where shoppers may be asked to provide information as part of a retail transaction, for example when paying by check or credit card, using a store's loyalty card or returning merchandise. We'll also look at ways that retailers might collect information without your knowledge, by using sophisticated technology.
Two California laws limit the collection of personal information in stores when you pay by credit card or check. These laws were enacted to prevent fraud and limit the amount of personal information which can be collected by merchants.
- When a consumer pays with a credit card, the merchant cannot record any personal information other than what is on the front of the credit card. (California Civil Code § 1747.08) (Song-Beverly Credit Card Act of 1971)
- When a consumer pays with a check, the merchant cannot record the credit card number. (California Civil Code § 1725)
What personal information can a merchant collect when a shopper pays with a credit card?
Under the Song-Beverly Credit Card Act:
- Merchants cannot request or require that the consumer write any personal information, including address and telephone number, on any form associated with the credit card transaction when the consumer uses a credit card to pay for goods or services.
- Merchants cannot ask the consumer to provide personal information that the merchant then records.
- Merchants cannot use forms with pre-printed spaces for personal information.
Are there any exceptions?
Yes. A merchant can collect personal information when:
- The credit card is used as a deposit.
- The credit card is used for a cash advance.
- The personal information is needed for something incidental but related to the use of the credit card. An example would be the address to which the purchased product is to be shipped.
- The merchant is required to collect information under a federal law or regulation.
- The merchant is contractually obligated to provide personal identification information in order to complete the credit card transaction.
- Merchants can record the cardholder’s driver’s license number or identification card number on any form associated with the transaction if the cardholder pays with a credit card but does not provide the credit card. An example is if you are at a department store and forget your credit card but want to charge something to your account.
- The card is used to "pay at the pump" for gasoline, limited to zip Code information which may be used solely for prevention of fraud, theft, or identity theft.
Does the law prohibit a merchant from asking to show identification when using a credit card?
The Song-Beverly Credit Card Act does not prohibit a California merchant from requiring a consumer who pays for goods or services by credit card to show identification such as a California driver’s license or California ID. If these are not available, another form of photo identification can be required to be shown. But merchants cannot write or record any information from these documents. However, as we explain below, the major credit card company rules provide that merchants cannot make showing identification a condition of credit card acceptance.
Does the law prohibit a merchant from asking for your zip code?
In Pineda v. Williams-Sonoma Stores, the California Supreme Court ruled that a merchant may not ask a customer to provide a zip code as part of a credit card transaction. Williams-Sonoma used customer zip codes that it collected from customers to obtain their home addresses. It then used those addresses to send catalogs to customers who had never provided their address to the retailer. It was able to obtain these addresses through a process known as reverse appending (reverse searches from databases in order to match their customers’ names and zip codes with their previously undisclosed addresses).
Exception: When "paying at the pump" for gasoline, your zip code can be collected. It may be used solely for prevention of fraud, theft, or identity theft.
What personal information can a merchant collect when a shopper pays by check?
Merchants who accept a check for goods or services sold or leased at retail cannot:
- Require a consumer to provide a credit card or record the credit card number in connection with any part of the transaction.
- Require a consumer to sign a statement agreeing to allow the consumer’s credit card to be charged to cover the amount of the check in case the check bounces.
- Contact the credit card issuer to find out if the amount of credit available to the consumer will cover the amount of the check.
Are there any exceptions?
Yes. A merchant can request or record a credit card number in connection with payment by check when:
- A check is used solely to obtain cash.
- A check is used as a deposit.
- A check is used to make a payment on that credit card account.
What happens when a merchant breaks the laws described above?
In California, merchants may be fined up to $250 for the first violation and up to $1,000 for each subsequent violation. In addition, the court can order the merchant to stop violating the law.
In most situations, a merchant may not condition acceptance of a Visa or MasterCard credit card upon the customer presenting identification. In other words, you can refuse to provide identification, and the merchant still must accept your credit card.
Be aware that identification may be required for purposes other than the credit card transaction, for example, when purchasing alcohol, tobacco products, or certain medications. Identification may also be required for unusual transactions flagged during the authorization process.
The MasterCard Rules (December 21, 2017 edition) provide as follows:
5.10.4 Additional Cardholder Identification
A Merchant may request but must not require a Cardholder to provide additional identification information as a condition of Card acceptance, unless such information is required to complete the Transaction, such as for shipping purposes, or the Standards specifically permit or require such information to be collected.
A Merchant in a country or region that supports use of the MasterCard Address Verification Service (AVS) for MasterCard POS Transactions may require the Cardholder’s ZIP or postal code to complete a Cardholder-Activated Terminal (CAT) Transaction, or the Cardholder’s address and ZIP or postal code to complete a mail order, phone order, or e-commerce Transaction.
The Visa Core Rules (April 14, 2018 edition) provide as follows:
18.104.22.168 Cardholder Identification
Unless specified in the Visa Rules, a Merchant must not request Cardholder identification as a condition of purchase.... a Merchant that suspects fraud in a Face-to-Face Environment may request Cardholder identification. If the identification is expired or does not match the name on the Card, or if the Cardholder does not provide identification, the Merchant may decide whether to accept the Card.
What should I do if a merchant insists upon seeing my identification?
Unfortunately, the MasterCard and Visa rules are often ignored by retailers. If you feel strongly about not showing identification as a condition of using your Visa or MasterCard credit card, you may wish to print out a copy of the relevant merchant rule (from the links cited above) and ask to speak to a store manager.
Can a retailer swipe my driver's license if I want to make a return?
Generally, yes. While return policies vary from one retailer to another, many retailers require you to present a driver's license (or government-issued ID) when you return or exchange merchandise. Typically, retailers will swipe your license in a reader that will query a database to look at your return history for patterns of fraud or abuse. By scanning your license, the retailer can collect any information that is encoded on the license's magnetic stripe or bar code. In most states, this information includes the data printed on the face of your license.
California law specifically allows a retailer to swipe your license "to collect or disclose personal information that is required for reporting, investigating, or preventing fraud, abuse, or material misrepresentation." CA Civil Code Section 1798.90.1(a)(1)(D).
Some retailers manage merchandise return data in-house. Others outsource the collection of this data to a company called The Retail Equation.
What is The Retail Equation?
The Retail Equation (formerly known as The Return Exchange) (TRE) is contracted by many retailers to gather and store their return information and analyze the data to develop return policies for those retailers. As customers return merchandise, TRE compares variables such as return frequency, dollar amounts and/or time against a set of rules that form the retailer’s return policy.
TRE states that it does not share its data among retailers. Access to information in their returns database is limited to the consumer, TRE, and the retailer that provided the data to TRE. In other words, TRE does not create a compilation of the shopper’s return activity across all merchants with which that individual shops. If the shopper has returned merchandise to several companies, a merchant will only see the returns for that specific retailer.
TRE does not actually set the return policies for participating retailers. The company gathers and supplies the data that subscribing retailers use to make return authorization decisions, and helps them determine their own return policies.
Can I see the information that The Retail Equation has about me?
Yes. You can order a copy of your Return Activity Report from TRE. This report is a history of all your return transactions posted in those stores that use TRE. The report lists return activity information including the stores you have returned to and, for each return, the date and time, whether it was with or without a receipt, and the dollar amount. You may obtain a copy of your return activity report by sending an email to: ReturnActivityReport@TheRetailEquation.com. You should include your name and a phone number where TRE can reach you. When TRE calls, the company will ask for your driver’s license number and state, to enable a database search.
Can I dispute the information that The Retail Equation has about me?
TRE offers consumers the ability to dispute their Return Activity Report. If a consumer identifies any inaccuracy in his or her information, or if a consumer needs to change information in TRE’s files, the consumer should notify TRE in writing at The Retail Equation, P.O. Box 51373, Irvine, CA 92619-1373 so that they can investigate and update their records.
Many supermarkets, drugstores, coffee houses, and other retailers offer customer loyalty and rewards programs. These programs generally use a card or app. Typically, shoppers need to provide their name, address, email address and sometimes other demographic information such as gender, phone number, birthday, or income to particiapte.
These programs allow the store to keep tabs on what customers buy and how often they shop. Merchants say this allows them to identify their most loyal customers, learn more about their buying habits, and offer such best customers the products and services they demand. However, some consumers and consumer-rights groups claim that the data collected by the stores violates privacy rights and may not even save consumers money.
If you shop in California, the Supermarket Club Card Disclosure Act of 1999 provides you with some protection. This law prohibits supermarket club card issuers (1) from requesting driver's license numbers or Social Security numbers, and (2) from selling or sharing personal customer information. The law defines supermarket very broadly -- as "any retailer that sells food items". There is, however, a limited exemption for membership card stores, such as Costco and Sam's Club.
Advertising Age Magazine has developed an interactive graphic that explains how information from a loyalty program is almost instantaneously shared with dozens of other companies.
The data broker Oracle Datalogix claims to have data including almost every U.S. household and more than $1 trillion in consumer transactions. This data comes primarily from loyalty programs at supermarkets and drug stores. By matching the email addresses or other personal information associated with loyalty programs to information used to establish Facebook accounts, Datalogix is able to track whether consumers purchase a product in a store after seeing a Facebook ad. Consumers can opt out of Datalogix-enabled advertising and analytic products by downloading Oracle's opt-out cookie.
Most consumers are aware that online merchants use various technologies that track their behavior when they shop online. This practice is known as "behavioral targeting." In addition, some online merchants engage in "dynamic pricing", charging different prices to different consumers for identical goods or services.
In the past, it was difficult for brick and mortar retail stores to engage in sophisticated tracking of their customers in the absence of the customer loyalty programs described in the preceding section. Online retailers have had the advantage of collecting analytical data through browser cookies and other mechanisms. Many technological advances now permit stores to track shoppers without their knowledge. The extent of such tracking had been a well-kept secret of many retailers. However, it seems that almost daily there are new revelations of tracking by retailers.
Perhaps the most shocking example involved Target, which was able to figure out that a teenage girl was pregnant before her father did. Whenever possible, Target uses a unique ID number (known internally as a Guest ID number) to identify its customers. Every time you use a credit card or coupon, visit the Target website, open a Target email, call Target customer service, or interact with Target in any way, Target associates this information with your Guest ID number. By data mining the pregnant teenager's purchase history, Target was able to know that she was pregnant because she purchased various items that were highly predictive of pregnancy. In addition, Target can link demographic information (such as your age, marital status, number of children, distance from the closest store, and estimated salary) to your Guest ID number. Target's data mining practices are both a fascinating and frightening story first revealed in a 2012 New York Times Magazine story.
Many new technologies are emerging to enable brick and mortar retailers to keep up with their online competitors. Innovative use of video surveillance and signals from mobile devices are rapidly helping to close this information gap. Retail stores are rapidly embracing these technologies, which create significant privacy concerns for shoppers. Retailers can detect when you look at a product, how long you stay in the store, track your movement through the aisles, and potentially recognize you as a returning customer. These retail analytics are rapidly changing traditional brick and mortar retail shops into "smart stores." Even shopping malls are following you when you shop.
How are mobile devices used to track you in retail stores?
Most mobile devices (including smartphones and many wearable devices) emit a Wi-Fi MAC Address and a Bluetooth address. Your MAC address is a unique 12-digit string of letters and numbers assigned to your phone or device. Retailers can use either their existing Wi-Fi or sensors placed throughout the store to detect your device's MAC address. This practice is known as Mobile Location Analytics (MLA) technology.
How can I prevent a store from tracking my mobile device?
To stop your MAC addresses from transmitting, you must either turn your device off or turn off both Wi-Fi and Bluetooth. Be sure to do so before you get close to the store, because the range of the retailer's sensors may extend beyond the store’s physical boundaries.
Remember that if you choose to use a retailer's Wi-Fi network, you will generally have to agree to its Terms and Conditions. You should be sure to read them before clicking "Accept" so that you can understand how your information may be used. Be aware that a retailer's Wi-Fi can capture your browser information, the URL of each page you visit, searches, products that you view on websites, and information that you enter into unsecured online forms.
What kinds of data do retail analytics companies collect about shoppers?
According to RetailNext, a company that offers real-time analytics to collect, analyze, and visualize in-store data, the following information may be collected:
- The location of a smartphone or wireless computing device is collected by observing Wi-Fi or Bluetooth signals broadcast from that device. Individual devices are identified by a unique number (called a “MAC address.")
- Data from video cameras is used to determine the paths people take through a physical space and to try to ascertain certain qualities about people, like age or gender.
- When customers use guest Wi-Fi “hotspots” at their locations, registration is sometimes required. Registration data from these services is collected.
- When customers use guest Wi-Fi hotspots, information about use of non-secure websites may include browser information, the URL of each page visited, search terms used, products viewed and saved on retail websites, and information entered into online forms.
How can facial recognition be used to track you in retail stores?
Video surveillance, typically used to deter shoplifting, can also be used to engage in facial recognition, whereby the approximate age and gender of a customer may be determined. This may be used to customize advertising to a customer's demographic. Video analytics can also ascertain where customers go in a store and which items they pick up. Facial recognition software programs continue to be adapted for retail environments.
