An On-Board Unit (OBU) is a device installed in a vehicle to enable electronic toll collection and other intelligent transport systems services. It communicates with roadside equipment via dedicated short-range communication (DSRC) or RFID, records toll charges, and may store account data for automatic payments. OBUs are deployed on toll roads, congestion charging schemes, and some public transit systems to reduce cash handling and improve traffic flow.

An Offshore Banking Unit is a bank branch or subsidiary located in a foreign jurisdiction designed to conduct international banking business with non-residents. OBUs operate under the host country’s regulatory framework and typically target non-resident clients and cross-border activities. They are used to access foreign currency markets, facilitate international trade, and may enjoy certain regulatory or tax conditions depending on local law.

Old Boys' Union, abbreviated OBU, is a term for alumni associations of schools, particularly in former British colonies. OBUs organize reunions, fundraising, mentorship programs, and social events to support students and schools.
