Credit Card Skimmers

gas pumpSkimmer use on the rise

Reports from around the country show increasing use of credit card skimming devices on gas pumps. The City of Madison weights and measures inspectors have set up a program to monitor local gas pumps for any illegal activity.

Gas pumps in the City of Madison are licensed and inspected for accuracy once per year. The dispenser's internal components are checked for security seals. At that time we look for skimming devices attached to the credit card reader wiring. Because of the alarming rise in skimming incidents, including many cases in Michigan, we will randomly check pumps for skimming devices throughout the year in addition to the yearly inspections.

Protect your customers from skimmers

Keep an eye on your pumps. If you see suspicious activity near a pump, have the pump checked for skimmers.

Have all upper cabinet locks keyed to a unique key that can only be used at that location. Whoever uses the key would sign a log book. That person would then be responsible for returning it. An exclusive key must be readily available at the station, with a copy maintained by the owner or corporate office.

Use tamper-resistant pressure seals Use tamper-resistant pressure seals that would be broken or destroyed if the upper cabinet is opened. A seal replacement policy, serial-numbered seals, and careful documentation are required for this process to work. If a seal is tampered with, a designated employee(s) would check the device for a skimmer, then replace the seal. The employee(s) would need training on skimmer identification and the station must maintain a stock of seals for this to work. Although this is a viable alternative, it requires someone to maintain the seals, which can be labor intensive. Keep in mind, anyone can purchase pressure seals online
