PCI DSS Terminal Inspections

Checking Credit Card Terminals Tampering

Regular inspections of credit card devices for tampering or skimmers is essential to protect UCSF and our customers, clients and patients from credit card fraud. Skimmers are devices criminals attach to legitimate card readers to steal your card information. Here's how you can check for skimmers:

Visually Inspect the Card Reader.

  • Look for any unusual or out-of-place attachments, parts, or loose components on the card reader.
  • Check for any extra wires, tape, or adhesive residue, as these could indicate tampering.
  • Check for Misaligned Parts:
  • Inspect the card slot for any misalignment, such as a card slot that appears thicker or wider than usual.
  • Wiggle the card reader and other parts to see if they are securely attached. A skimmer may be loose.

Examine the Keypad.

  • Look for any suspicious overlays on the keypad, as criminals sometimes place fake keypads over the genuine ones.
  • Press each button on the keypad to ensure they all feel uniform and responsive.

Inspect the Card Slot.

  • Gently tug on the card slot to see if it's securely attached. Skimmers are often held in place with adhesive or double-sided tape.
  • Look for any noticeable scratches, glue residue, or damage around the card slot.

Check for Hidden Cameras.

  • Scan the area around the card reader for any unusual or hidden cameras. Criminals use these to capture your PIN as you enter it.

Reporting Suspected Skimmers
