Discovery
Datajacks were installed in the first human in the year 2080 by BioTechnica who still produce and maintain nearly all dataports in existence. After their discovery it took nearly a full century before datajacks had been installed into virtually everyone as the world moved more and more online.
While BioTechnica pushed to have them mandated by the government, the Lords of Night still had an active role in Acostead and banned the forced installation. However, this did not last long though as the corporations seized more and more power in the large cities.
Availability
Datajacks are commonly used by nearly all of humanity, as it has become the only way to interact with anything in the bigger cities like Acostead. However there are still some pockets of people who refuse to get one, believing that it is the final step before giving up who are you as a person.
These people only exist though in the smallest of communities who still partake in bartaring and other outdated activities, and have no access to the incredible tech the large cities have to offer. They are however, mostly free of the ever-watching corporations who are constantly analyzing every piece of data received and sent to datajacks.
Complexity
Datajacks are fairly simple when compared to some of the tech available in Acostead. They utilize a small port that is typically placed in the wrist, though they can be installed virtually anywhere. Each datajack consists of a thin fiber optic cord that can be connected to dataports regardless of make or model.
Information received through the datajack is then transferred directly to the user brain via a network of microscopic fibers that run through the nervous system. Because of this, humans and technology are now interlinked, resulting in the heightened need for cybersecurity to protect not only data but also brains themselves.
Mechanics
Players with datajacks installed can connect to dataports and access their information if they are unencrypted. They can utilize these dataports to do numerous things including accessing the Net, purchasing items, access information, and numerous other activities.
If a player accesses a dataport that is encrypted and they lack the proper credentials they can attempt to hack the dataport. To hack the dataport, they must succeed a Technology role against a DC set by the DM. Players who are proficient with hacker tools have advantage on all Technology roles involving hacking.
