Because every New Jersey online casino operates under an Atlantic City casino's permit, you can usually move money in person. DGE rules allow a deposit of cash, gaming chips or slot tokens at a cashiering location approved by the Division, and a cash-out at the cashier's cage when a known patron requests it, regardless of how you deposited. See N.J.A.C. 13:69O-1.3.
In practice this means visiting the cage at your brand's partner casino, for example Borgata for BetMGM or Golden Nugget for FanDuel, with photo ID that matches your online account. Not every online brand supports cage transactions, so ask before you travel.
It is the one method with no third-party processor in the middle, and it gets cash in your hand the same day. The obvious limit is that you have to be in Atlantic City.
A cage cash-out is still a withdrawal from your account, so the operator's usual identity checks apply.
