These 3 states are the first to ban 'surveillance pricing' that uses personal data to charge more

Connecticut, Maryland, and New Jersey became the first states to enact laws restricting companies from using personal data such as browsing history or shopping habits to set individualized prices, with Maryland's law taking effect October 1 and New Jersey and Connecticut laws already signed.

The three laws take different approaches to enforcement and coverage scope; retail and technology groups have argued overly broad restrictions could interfere with legitimate discounts and be costly to comply with.
