Fence

 is a trader in Escape from Tarkov.

Biography
The conflict had barely started when Fence began setting up anonymous outlets for buying and selling goods. Keeping incognito, he nevertheless managed to put together a well-organised smuggler network, operating all over the Norvinsk region.

Loyalty Level Requirements
In contrast to other traders, Fence's reputation and loyalty level is not raised through quests and sales, but by raising your Scav karma. The higher your reputation, the better the payout for items sold to Fence will be. If you achieve Scav karma level 6, you will also get access to an additional sales tab that offers a 30% discount.

Trivia
According to the changelog of patch 0.12.11.0.13074, which introduced the Scav karma system, Fence's additional sales tab is supposed to include "uninsured items lost by other players". This mechanic is currently either disabled or broken, as no gear that looks "player made" has ever been seen.
