ID check required before showing?

Maybe I misheard, but someone that uses Checkpoint ID told me that, in certain states, you have to verify prospects' government IDs on-site prior to showing them an apartment. Is anyone familiar with these regulations? I thought it was just to catch fraud. 
 

In Texas, it is a requirement to provide ID prior to touring in person. In the 80s or 90s someone was assaulted during a property tour and I'm pretty sure that is the reason for the ID requirement now.

In Washington State, we have to see and record their government ID. I personally make a copy and leave it on my printer.

Requiring IDs actually started in the late 70s after several leasing consultants were assaulted/raped in model apts. Word spread fast, Realtors as well as on site team members were alarmed. This is the best way to handle it; have a small sign on your desk/or on the wall in plain view. "In order to tour this property, please provide a current, government issued, photo ID." And yes, if this ID is issued in another country and is current you should accept it. DO NOT ask for a 'Drivers License'; blind people don't have one. Don't ask for a 'photo' ID or you will have to accept a Costco type card. If you leave the ID in or on your desk/in a drawer while showing, don't forget to give it back. No reason to copy it, you could be accused of racial/color discrimination. Check with local Housing Authorities for city and state guidelines.
