From Rooted in Rights' Electronic Visit Verification: a Threat to Independence For Disabled People:

"The big thing about EVV that's causing alarm is the use of GPS tracking and in some cases cameras and microphones, especially in Ohio, which has rolled out what Kendra Scalia of Stop EVV describes as the "most onerous" version of EVV (the state claims cameras on the devices have been disabled). GPS tracking tells the government where services are delivered...but it also tells the government where disabled people are going.  EVV data can show where disabled people go to church, school, or shop, and this compromise of privacy extends to family too - Melissa Milinovich, another Ohio consumer, has a young daughter and EVV will allow people to effectively track her child."
