1 Fake SIN? Try like.... 4.
The number of those depends on the character really. Some should have 1 some should have umpteen and still some shouldn't have any.
As a hacker I just steal other people's commcodes when I do just about anything, but then again unlike the face I'll almost never be called on to broadcast a SIN, even if I have a legal one.
Commlink (Battle Buddy Basic usually)
Gear,
Gecko Tipped grenades with Neuro Stun, 2 or three of those
An Ares low intensity laser
Vacuum sealer unit, for fresh fish whenever I need it, or grenades and bullets.
Form fitting body armour, always. YNT Softweave on most all my armour just because "Evo made it with me in mind", optionally a full chemical seal, just keep the helmet in a bag.
Camouflage suit or Stealth Suit with thermal damping and a ballistic mask and helmet (If I'm on the job)
H-Jumpsuit, Holo gloves and hood, or just an Urban Explorer
Trodes Nanopaste or otherwise, AR gloves or wristboard, micro microphone and some headphones
Goggles or contacts
Onotari Equalizers or other preferred side arm, Cavalier Deputy or Sheriff usually
Datachips sewn into my underwear
an IC with a good analyze running constantly
Smart ammo pouches, at least 4 of these loaded with sidearm ammo
Shock Gloves
a small drone with a directional antenna and a retrans unit
Gecko Gloves
Can of Barrier foam, works as spray on handcuffs or for blocking doors in a hurry, kind of thing.
Integrated sensors of various types
At home
A small armoury's worth of guns and ammo (Plastic Wrapped)
A couple crates of neuro stun grenades and similar (Plastic Wrapped)
Entertainment System's Cyclops (Also Plastic Wrapped)
Some sort of automated security.
Depending on the character I might employ some WP Grenades for cleanup
Various sensor defeating webbing, for stakeouts
Nutrikrill 4500 food processor
something like that
