I’m just gonna shove a handful of suggestions here, relating to cash cards and more common use of the computer skill as well as general hacking.
Purchasing Gasoline: The pumps at most (if not all) gas stations should be locked unless the player uses a console behind the gas station counter to purchase some gasoline with a cash card. The player can then walk outside to the pumps and obtain the amount of gasoline they specified. Of course, the console could just be hacked to just unlock all the pumps as well.
Guns n’ Ammo Vending Machines: Considering how easily the average citizen can get their hands on weaponry in the Pre-Cataclysm, I wouldn’t see why there wouldn’t be vending machines that dispense low-caliber ammunition and perhaps some smaller firearms. These would obviously be located in gun stores, and constructed with stronger materials so it could withstand a grenade blast. Really persistent characters could go at the thing with a pickaxe for a few hours, and characters with high computer skills could just use an electrohack to unlock the machine for ‘restocking’.
Cracking ATMs: ATMs already exist inside banks, so why not give players the ability to crack ATMs with their hacking abilities and highly inflate the balance of their bank account? This would obviously have to require very high computer skill in order to access millions of dollars, of course the use of said money is rather limited.
