Hacking goggles.
It’s 3 pieces of equipment: The eyewear, The gloves, and the battery pack. The battery pack has a charge of about 3 days but will eventually need to recharge. The way the device works is, the wearer must first touch the device he or she is hacking. The eyewear then projects the code before the user. The gloves can manipulate the code or create a whole new program to insert into the original coding. The gloves can store pre made programs, and then retrieve them when need be. When done manipulating the code, swipe your hand over the eyewear. The new coding will then be placed in the device. Recommended practice. It takes time how to learn this, but is much faster than the original way.
Strengths: Much faster, easier to use, doesn’t have to be at the terminal or device, can be easily concealed.
Weaknesses: Charge running out, takes longer to learn.
Also you might look a little funny with your hands swinging at “nothing”, but your friends will enjoy your work and your enemies will need to upgrade their systems.
