Frequently asked questions
Eligibility, value, expiry, privacy, and safe use—explained simply.
For the USC community. Not affiliated with or endorsed by USC.
Who’s eligible?
Guests who spend $25+ in one transaction and receive a distinct code at checkout. Each eligible physical card grants once, and one account may add multiple distinct cards.
Is this official USC?
This promotion is offered by YGF for the USC community and is not sponsored, endorsed by, or administered by the University of Southern California.
When do credits expire?
A successful new-card top-up sets the whole wallet to expire 14 days later, including older remaining Credits. Retrying the same code does not extend expiry.
Do I need a school email?
No. Scan first to use a private guest wallet. Sign in with Google or Apple and combine the wallet only for recovery, cross-device access, or an Agent API key.
