Email – Most companies don’t offer email readings because it makes it harder for the psychic to pick up on your ​energy and to retrieve answers from the spiritual realm without being able to hear your voice or see your face.  The way email readings work is you submit your questions through a form, and then you’ll receive answers in your inbox within 24 hours.  
All biometric readers work similarly, by comparing the template stored in memory to the scan obtained during the process of identification. If there is a high enough degree of probability that the template in the memory is compatible with the live scan (the scan belongs to the authorized person), the ID number of that person is sent to a control panel. The control panel then checks the permission level of the user and determines whether access should be allowed. The communication between the reader and the control panel is usually transmitted using the industry standard Wiegand interface. The only exception is the intelligent biometric reader, which does not require any panels and directly controls all door hardware.
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.
