Hardpoints are a representation of an Item or Entity's ability to install and retain technology such as Cyberware, [Components] or Mods.
Characters may install Cyberware on their body so long as they have enough Hardpoints available to pay the Hardpoint Tax
In addition once 10 Hardpoints have been utilised on a Character by installed Cyberware they become so chromed out they gain the Technological Physiology and all the rules that would apply to having such a Physiology.
