Based on the manufacturer’s information, TouchPoints emits an infrared-based electromagnetic field (EMF) for about 30 seconds when you power up the device, as well as during the pairing process.  Additionally, the haptic engine that allows the device to vibrate emits a magnetic field with every pulse (vibration). I measured a reading of 22 mG with my EMF meter, which is relatively strong compared to the magnetic fields you would find elsewhere in your household. The good news is you don’t have to use TouchPoints for more than two 20-minute to 30-minute sessions per day, which limits your EMF exposure.
