The United States Secret Service, in collaboration with the police departments of Hialeah and Homestead, successfully confiscated 13 illicit card cloning devices from businesses in South Florida. Dubbed "Operation Heat Check," this initiative, according to an official statement released on Wednesday, prevented potential fraud losses estimated at $13.5 million.
The Strategy Behind Operation Heat Check
Operation Heat Check combined widespread inspections of establishments with an outreach campaign targeting business owners themselves. During the operation, agents visited 378 locations throughout the Miami area, conducting 2,842 inspections of point-of-sale terminals, gas pumps, and ATMs.
In addition to removing the 13 illegal devices, teams distributed educational materials to help business employees identify cloning devices and better safeguard their customers. The initiative also targeted fraud related to the Electronic Benefits Transfer (EBT) system, which millions of families rely on for food assistance.
Understanding Card Cloning Devices
Skimmers are covertly installed by criminals on ATMs, gas station pumps, and retail payment terminals. Once in place, they capture the victim's card data without their knowledge, enabling the perpetrators to make fraudulent purchases, withdraw funds, or copy the stolen information onto a new card.
The impact is particularly severe for those depending on EBT benefits to purchase food and essential items. Starting December 20, 2024, stolen SNAP funds through cloning will no longer be federally reimbursed. Criminal organizations utilizing these devices often move swiftly across communities and jurisdictions, necessitating coordination among federal, state, and local agencies.
Future Actions According to Authorities
Michael Townsend, the special agent in charge of the Secret Service's Miami office, emphasized the preventative nature of the operation: "Partnerships with law enforcement, businesses, and our communities are crucial to dismantling these crimes and protecting the public."
Operation Heat Check is part of an ongoing national program by the Secret Service to combat payment card data theft and EBT fraud. In July 2025, a similar operation in Miami-Dade and Broward visited 613 businesses, inspected over 4,700 terminals, and recovered 10 devices, preventing estimated losses of $12.4 million.
Eddie Rodríguez, spokesperson for the Hialeah police, made it clear that this week's events are just the beginning: "Through this operation comes investigation, arrests... So this is only the start of a very large investigation."
Why South Florida Is a Frequent Target
The Secret Service's official statement was candid: "Miami is a global city, home to millions and one of the most visited destinations in the United States. This visibility also makes South Florida an appealing target for criminals seeking to exploit hardworking consumers and businesses."
In January 2025, two Cubans were arrested in Tampa with cloning devices and fraudulent cards. In May of this year, Orlando police dismantled a card fraud network linked to 37 incidents between October 2025 and April 2026, with over $5,180 in SNAP funds lost. In July, four men were charged in the Southern District of Florida for diverting over $19 million from the SNAP program between 2019 and 2026.
