In this article, we will guide you and your volunteers through using the Check-In Tool
The check-in tool helps you manage all your event attendees in one place — checking them in, linking them to their carts, and keeping everything organized.
Overview of How it Works:
When an attendee is linked to their Trellis account (by email), you can use the Check-In Tool to:
-
Securely save payment info.
-
See and manage the same cart, in real time.
- Process payments at the end of the night.
What If They're Not Linked?
No problem — you can still check them in and manage their cart. But here’s what to keep in mind:
-
They won’t see the cart you’re building for them.
- You won't see anything they add to their cart themselves, from their phone.
-
You can’t complete their purchase until they provide an email.
Best Practice
Try to collect an email up front — it saves time, avoids confusion, and makes checkout smoother for both sides.

Understanding an Attendee's Status
To have the best event experience, you will want to link all of your attendees to Trellis user accounts, using their email address. The Check-In Tool will flag whether attendees are linked or not.
1. Linked Attendees:
These attendees are linked to user accounts via their email and are ready to be checked in.
Full functionality is available:
- Check in
- Update attendee info
- Manage shared cart between you and attendee
- Save payment methods
- Complete purchases
2. Unlinked "Reassign" Attendees:
These attendees are missing a unique email address, and therefore cannot be linked to a user account.
If two or more attendees have the same email, one attendee will be linked and the others will say "Reassign".
Available functionality:
- Check in
- Manage local cart
- Complete purchases by entering in a credit card for one-time use
- Update attendee info
Unavailable functionality:
- Save payment methods
- Manage a shared cart between you and that attendee
3. Unlinked "Verify" Attendees
This attendee needs to take an authenticated action on Trellis to confirm their identity. This is to prevent a bad actor from entering in email addresses and gaining access to credit card data without the donor's consent.
Available functionality:
- Check them in
- Manage local cart
- Complete purchases by entering in a credit card for one-time use
- Update attendee info
Unavailable functionality:
- Save payment methods
- Manage a shared cart between you and that attendee
- Clicking on a verification link in their email (sent from check-in tool)
- Bidding in a silent auction
- Making a purchase while signed in
- Note that signing in with a password is not considered an authenticated action.
How to Check-In a Linked Attendee
- Search for the attendee by last name (recommended), email address, or phone number.
- Once found, confirm that attendee is Linked.
- Confirm the information on file with the attendee:
- "Can I confirm your email is [email] and your phone number ends in ####?"
- Click the blue Check-In button to check the attendee in.
- The system will then email and text the attendee a sign-in link. Ask the attendee to click on the link on their device to sign in.
- The text says "Welcome to [Fundraiser Headline]! Your table number is [##]. Here's your one-time login link to your account: [url]"
- If the attendee does not have a phone number saved, the system will prompt you to enter a phone number.
- If the attendee does not have a credit card saved to their account, the system will prompt you to enter a credit card.
- Add a credit card to the attendee’s account by completing the form.
- Hit Confirm and then you can now move on the next attendee!
Pro Tip
Make sure to save a credit card during check-in to simplify the event experience for you and your attendee.
At this time, our system does not integrate with credit card scanning hardware.
How to Check-In an Unlinked Attendee
If the attendee says “Reassign”, it means that their email address is already being used by another attendee.
Please Note:
Attendees must have a unique email address to be linked to a user account.
Spouses cannot share email addresses.
- Search for the attendee by last name (recommended), email address, or phone number.
- If the attendee is not found, search under the name of whoever purchased tickets.
- Once found, confirm that attendee status is Reassign.
- Click Check-In to start the process.
- The system will prompt you to edit the attendee.
- Click Edit Attendee to add the correct information.
- Make sure you get the Full Name, a unique Email Address, and a Phone Number for the attendee.
- You should also gather Mailing Address in order to issue tax receipts using Trellis.
- Once the attendee's information is edited, click Save and Check-In.
- The system will then email and text the attendee a sign-in link. Ask the attendee to click on the link on their device to sign in.
- The text says "Welcome to [Fundraiser Headline]! Your table number is [##]. Here's your one-time login link to your account: [url]"
- If the attendee does not have a credit card saved to their account, the system will prompt you to enter a credit card.
- Add a credit card to the attendee’s account by completing the form.
- Hit Confirm and then you can now move on the next attendee!
How to Check In an Unverified Attendee
If the attendee says “Verify”, they'll need to verify their email address before you can save a payment method.
This prevents unauthorized users from accessing their account and keeps their information secure.
- On an attendee that says "Verify", confirm with the attendee that the email address and phone number on file are correct.
- Click the blue Check-In button.
- The attendee will be checked-in, and the system will automatically send a verification link to the attendee’s email and phone number on file.
- Ask the attendee to click on the link in the email or text.
- Once the attendee clicks the link, they will be signed into their account on their device, and the attendee status will change from unverified to verified.
- You can now use the buttons under the attendee to add a credit card and manage the attendee’s cart.
Please Note:
If the attendee does not receive the email verification link, please ask them to check their spam folder.
Text messages are less likely to be blocked by spam filtering. You can always resend a verification link by clicking View More on the attendee, then Send Verify Link.
