Gift Cards

Petty Cash

With the rollout of Greenphire’s prepaid card program, the University is migrating away from opening new petty cash bank accounts. Requests for new petty cash bank accounts will be evaluated on a case-by-case basis by the JHU Treasury Office. Petty Cash Tills, for study program reimbursements less than $500, may still be created by submitting a request to the Treasury Office at [email protected].
