This article is about the Manga version of the Transmitters. For alternate pages referred to by this name, please click any of the icons above. Transmitters are small round microchips that are stapled into the back of the left ears of all the orphans at Grace Field House. The use of these transmitters help a caretaker to track down the whereabouts of an orphan via a radar. Shortly after being transplanted into their ears, the transmitter appears to be a small red bump underneath the skin, similar to a mosquito bite. However, the visibility of the transmitters underneath the skin fades and disappears over time. Their true form is unknown because they are not externally visible. The orphans are told the red bumps on the back of their ears are from where a doctor took their blood to test for diseases when they were babies.

Operation[]
Transmitters are applied to infants before being sent to a farm. They are applied by some kind of stapler, leaving a small scar on the back of their ear, which disappears as the ear heals over time.
The transmitters work as some kind of safety measure for the Mamas and Demons because they can monitor the location of the orphans with the use of a radar. The transmitters are undetectable by the children unless it is newly implanted, and it is possible to see the needle mark. If the transmitter is destroyed, it will send a notification to headquarters. This is not the case if the transmitter is removed or disabled.
Disadvantages[]
Although they are of utmost confidence of the "Demons", the transmitters have some disadvantages. First, the transmitters do not release unique identification signals, meaning the radar user cannot determine which child is being detected. They also do not send any alarms or notifications if a child goes near the fence or the gate.
After six years of study and experiments, Ray discovered a way to turn off the transmitters. Using gifts he earned from Mama Isabella for being good, such as handheld video games and other things he asked for, Ray was able to create a device that could disable the transmitters by putting it up to the ear and pushing the button.

Trivia[]
- The transmitters were possibly created after 2015 as Ray affirms that at that time there was no technology that could create them.
- Isabella told the children that the mark left from implanting the tracking device was a mark from when they had their blood drawn.
