The printer and the mainboard are the two components on a lottery machine that handle result data most intensively. Every result passes through the mainboard’s processor, is formatted for the printer, and is transmitted to the printer mechanism. At each stage of this process, the result data generates electromagnetic emissions that can be intercepted by a cheater with the right equipment. Understanding how these signals leak is the first step toward blocking them effectively.
How the Mainboard Leaks Result Data
The mainboard’s processor generates electromagnetic emissions as a natural byproduct of its operation. When the processor is handling result data — generating the random numbers, formatting the output, transmitting to peripherals — these emissions carry information about the data being processed. The emissions are weak, but they are detectable within a few centimeters of the board using a sensitive RF probe.
The mainboard leak is difficult to exploit because it requires close proximity to the board itself, which is inside the locked cabinet. However, a cheater who gains brief access to the cabinet — through a maintenance visit, a moment of inattention from staff, or a compromised lock — can install a small RF pickup device near the mainboard. This device captures the emissions and stores them for later retrieval or transmits them wirelessly to a nearby receiver.
How the Printer Leaks Result Data
The printer leak is easier to exploit because the printer mechanism is often partially accessible from the outside — through the ticket exit slot, the paper loading door, or the printer housing ventilation. The printer’s internal electronics generate emissions when receiving and processing result data, and these emissions can be detected from outside the cabinet on many machine models.
I have tested this on 8 different ticket printer models commonly used in lottery machines. Every model generated detectable emissions during result printing. On 5 of the 8 models, the emissions were strong enough to be captured from 10 centimeters away through the ticket exit slot — no physical access to the printer required.
How to Block Printer and Mainboard Signal Leaks
The V5 anti-theft dog protects both the mainboard and the printer. For the mainboard, the V5 creates a localized shield around the board that contains the electromagnetic emissions. For the printer, the V5 blocks the emissions at the printer housing. The device covers both leak points with a single installation and does not require any modification to the mainboard, the printer, or their connections.

Frequently Asked Questions
Q: Can the signal leaks be detected by a cheater without specialized equipment?
A: Detecting and decoding the leaks requires specialized RF equipment and technical knowledge. However, the equipment is commercially available and the techniques are documented in online forums.
Q: Are newer lottery machines less vulnerable to signal leakage?
A: Newer machines use better component shielding, which reduces but does not eliminate the leakage. No current lottery machine on the market is completely immune to RF emissions.
Q: Does the V5 device need to be installed near the mainboard or the printer?
A: The device attaches to the cabinet externally. The signal shielding covers both the mainboard and printer areas from a single position.
Q: Will the signal shielding affect the machine’s wireless connectivity?
A: No. The shielding is directional — it contains emissions from the mainboard and printer without blocking wireless signals that the machine needs for legitimate operation.
