Which online services offer secure and fast notarization?

Recently, I needed to draw up a power of attorney for a friend who lives in another city. At first, I thought about going there myself, but I didn't have enough time. I decided to give https://onenotary.us/ a try, even though I was skeptical. It turned out to be convenient: I uploaded the documents, the notary checked them online, and I signed them electronically. The whole process took less than half an hour, and I realized that sometimes technology really does make life easier without unnecessary bureaucracy.
