Access Cards are needed to open chests in structures in the open world. Some chests don’t require these cards, but some do. Usually, such chests contain more valuable rewards. The chests, as well as Access Cards themselves, have grades. A card must match a chest by grade, otherwise you won’t be able to unlock it.
How to Get Access Cards
- Access Cards can be bought from the Armorer NPC (usually, 2 units per hour).
- Sometimes (quite rarely), you can buy Access Cards from the Trading Terminal on Space Stations in space and in cities on planets (so far, I’ve seen up to 100 units on sale).
- Access Cards can also be found in chests, although quite rarely.
Additional Tips
You should buy and have as many Access Cards as possible because they allow you to easily farm almost any resources and materials you need, flying from structure to structure on a suitable planet. For example, you can easily find Higgs Boson, Antimatter, Glowing Ores / Ingots, top-tier equipment, and other useful items just by opening chests on a planet of level 25.
