Purpose of this training
The Department of Agriculture and Markets Bureau of Weights & Measures wants to eliminate, or at least drastically reduce, the presence of illegal skimmers from devices it regularly inspects. To accomplish this, the Bureau is requesting municipal W&M agencies to check retail motor fuel dispensers for skimming devices.

Authority
W&M will be checking for skimmers as part of a statewide effort to identify these illegal devices and bring them to the attention of the police. W&M will use their technical knowledge of retail motor fuel dispensers to identify but it is the police who will investigate and pursue legal action.

Card Reader Cabinet
This is where we are looking. Some dispensers have
separate cabinets for card reader and paper roll for receipts.
Examine the cabinet for tamper‐evident seals.

Tamper-evident seals continued
If the cabinet has an unbroken tamper‐evident security seal in place and the station has replacement seals, use your best judgement in deciding if you should check. If the seals are serially numbered be aware that this number may be recorded and it may be best to not check. We do not want to disrupt any security measures that the station already has in place.

Tamper-evident seals continued
If the station does not have replacement security seals do not break the seals.
If the station has tamper‐evident seals check all the seals for evidence of tampering.
If a cabinet has a broken tamper‐evident security seal in place notify the station owner/manager and check for a skimming device.
