> How do they connect my credit card data to my Google activity?
Most people have a phone number with google for gmail (you didn't need one in the beginning, but do now). There's also their wallet, app store, voice, broadband, phone plan, etc.
Some people will dodge all of that, but most won't.

- avocado4 7y agoEven if they do (for Android users only), how would they connect location data to my credit card history? Are you claiming that Google reverse engineers PII by correlating Android location data with credit card purchase location history?
- dehrmann 7y agoThis doesn't quite say they do exactly that, but they do tie location data to offline purchases. > Since 2014, Google has flagged for advertisers when someone who clicked an ad visits a physical store, using the Location History feature in Google Maps. Still, the advertiser didn’t know if the shopper made a purchase. So Google added more. A tool, introduced the following year, let advertisers upload email addresses of customers they’ve collected into Google’s ad-buying system, which then encrypted them. Additionally, Google layered on inputs from third-party data brokers, such as Experian Plc and Acxiom Corp., which draw in demographic and financial information for marketers.

- dillonmckay 7y agoIf you use a loyalty card, then definitely.
- dillonmckay 7y agoThey know your approximate location when you conduct an offline credit card transaction, and the approximate time and location of the store where the transaction occurred.
- CarlRJ 7y agoAnd while one such data point pair isn't conclusive, getting, say, a dozen matching pairs might identify a user with high enough correlation to be useful.
- avocado4 7y ago> Most people have a phone number with google for gmail (you didn't need one in the beginning, but do now) I just created a new Google account without a phone number 10 seconds ago. Phone number was optional and of course I didn't provide it.
