The mainstream types of chipless tags are digitally encoded and work at more than one millimetre range, like silicon chips. Their potential markets go beyond the lowest cost-highest volume potential markets because they have other attributes beyond cost.
or red shift. noun, Astronomy. 1. a shift toward longer wavelengths of the spectral lines emitted by a celestial object that is caused by the object moving away from the earth. Compare cosmological redshift, Doppler effect, gravitational redshift. Origin of redshift.
Hubble Law. More distant galaxy has greater redshift. If the distance is measured in units of megaparsecs (Mpc) and the recession speed is in kilometers/second (km/sec), the Hubble constant (slope of the line) is between 70 and 80 km/sec/Mpc.
