New Yorkers who receive a card after they're implemented in September will find contact information for the Civilian Complaint Review Board — the agency responsible for investigating New Yorkers' claims of police misconduct.

"These receipts are clearly designed to invite retaliatory complaints against police officers who make an active effort to prevent crime and take guns off the street," Lynch said in a statement.

The cards will also require officers to list their name, rank, badge number on the card, which indicates why the officer stopped an individual.

"They are just one more item on the ever-growing list of anti-public-safety measures that will put an end to proactive policing in this city and ultimately accelerate the increase in crime and disorder that we are already seeing in our public spaces," Lynch added.

The cards are one of a handful of reforms approved by the federal court after New York City over stop-and-frisk measures by NYPD that critics said disproportionately targeted young men of color.
