Here's a quick guide on Clue Exchange and Credits in Arknights: Endfield.
Seven different clues are all that stand between an unfinished board and a useful Credit payout in Arknights: Endfield. The trouble is that your operators won't always find the one you're missing. That's where exchanging clues with friends helps.
The Reception Room handles this system aboard Dijiang. Check it alongside your production cabins for extra resources.
How to Gather Clues
Assign operators to the Reception Room and let them search. Their base skills can improve clue gathering, so check those effects when choosing staff. Collect completed clues and place the different types on your board.

You need all seven types for a complete set. Several copies of the same clue won't fill another faction's slot. Keep track of your missing numbers so you know what to look for when friends send gifts.
How to Exchange Clues With Friends
Send spare clues to friends who need them. Donations award Credits, with a better payout when the recipient is missing that clue. Check their board status before choosing someone instead of sending every duplicate to the same person.
Received clues can help complete your own set, but they have an expiry timer and can't be passed along again. Use gifts that are approaching expiry before equivalent clues from your own collection. This keeps useful donations from disappearing unused.

How to Start a Clue Exchange
Place one of each of the seven clue types, then start the exchange from your Reception Room. The exchange runs for 20 hours. Friends can visit and participate while it's active, and you collect the host reward afterward.
Your room level affects the base host payout, while participation adds more Credits. You can also visit friends with active exchanges for rewards of your own. Check the icons on the friends list to find available visits quickly.
How to Spend Credits
Open the Acquisition Center and visit the Credit Store. Check the daily offerings and discounts, then buy resources that support your current upgrades. Credits are a separate currency from T-Creds, even though the names sound similar.
Only 300 Credits carry over through the daily reset, so spend any excess beforehand. Production Assist visits provide another daily source. Combine those visits with your clue exchanges.
Collect seven different clues, share useful duplicates, and spend excess Credits before the daily reset.
