few questions to those familar with whid cactus injector ,proxmark and chamelon

[pyratemade]

ive been reading on these tools for quite sometime but havent found anyone who is more on the 'blackhat' use of these tools shall i say
my questions about the whid cactus injector is it even still relevant i havent notice it having updates for quite sometime has it ied just as the rubber ducky or is it just up to oneself to write own payload and such for i was looking at this hardware in order to infect an office computer system and steal all access information to be able to access later on at different location is this possible with this tool? or could reccomend something better

as for the proxmark it having a distance range is this able to grab cc data or perhaps steal hotel room key data and if so would i be able to do at a distance say just walking buy as someoone is usisng their key or could i just sniff putting it up against the key reader my same question is pretty much for the chamelon to with its abilit to emulate would i hav to use directly upon key making a copy thn save and emulate or perhaps can it sniff from the key reader on door and emulate this way any information is much appreciated yes i an bew to this area and would apprciate any free help i i will also offer fullz with dl id for good advice o guidance thanks

Regarding your first question, I'm pretty sure they faded in to obscurity after being embarassed at one of the vegas cons (the last one before the pandemic maybe?)
As far as assgrabbing goes that might be fun to play around with in EU but as far as the States go most of all cool shit isnt rfid
