Boris Johnson says he wants everybody to take “enabling tests” for “the virus” at the beginning of every day. (Click that link to hear him say it.)
Ways that can work:
1. Everyone is microchip-implanted, and the testing technology shakes hands with an implant when it takes the blood sample, verifying somehow that the implant and the sample are in the same person’s body.
2. The technology checks the DNA fingerprint of the blood sample that it runs the viral antigen test on. (Be aware that cutting the strands of DNA into pieces as is required for a DNA test currently takes at least a few hours.)
3. Any other suggestions? (A system relying on voice recognition, an iris scan, or other non-intrusive biometrics such as face recognition, would be easy to beat. For example, just show another person’s face to the camera when you stick your finger in the finger-prick device.)
