As revealed at this weekend's QuakeCon, Fallout 76 will indeed have microtransactions, and it will also have PERK Cards - which give players new perks to slot into their characters. But you can all exhale, because PERK card packs will only be earned in-game via leveling up, and not with real money.
Bethesda's Pete @DCDeacon Hines took to twitter to clear it up this weekend:
In #Fallout76, Perks are represented through Perk Cards. You earn them every time you Level Up.
Earn Perk Card Packs solely through leveling up. Every other level up to 10, and every 5 levels after. pic.twitter.com/JRRHFRLNk8

You just get them when you level up.
