After Valentine's Day, it only got stranger. Callers asked about lost jewelry and I'd instead tell them about their children or partners, which only pissed them off. HR called and told me to stop doing that—if someone wanted "remote viewing," I was to tell him or her to call a psychic who had that skill listed on their profile. I was, and still am, impressed by how seriously my employer treated "real psychic powers" instead of just racking up minutes. But I also noticed that bad reviews never made it to my profile or anyone else's, which sickened me.
In the 1-to-many mode a user presents biometric data such as a fingerprint or retina scan and the reader then compares the live scan to all the templates stored in the memory. This method is preferred by most end-users, because it eliminates the need to carry ID cards or use PINs. On the other hand, this method is slower, because the reader may have to perform thousands of comparison operations until it finds the match. An important technical characteristic of a 1-to-many reader is the number of comparisons that can be performed in one second, which is considered the maximum time that users can wait at a door without noticing a delay. Currently most 1-to-many readers are capable of performing 2,000–3,000 matching operations per second.
I dug them out again this spring for a foray into a career as a phone psychic—the latest installment of “Human Guinea Pig,” a column in which I am supposed to explore intriguing corners of life, but in which, so far, I mostly humiliate myself. (Like here, for example.) Locating openings for my extrasensory services was easy. I went to an online job site and typed “psychic” into the search engine. I sent e-mails to the three companies listed, and two—I’ll call them ESP Net and Chakra Con—sent me back contracts to fill out.
