'''OBEX''' (abbreviation of '''OBject EXchange''', also termed '''IrOBEX''') is a [[communication protocol]] that facilitates the exchange of binary objects between devices. It is maintained by the [[Infrared Data Association]] but has also been adopted by the [[Bluetooth Special Interest Group]] and the [[SyncML]] wing of the [[Open Mobile Alliance]] (OMA). One of OBEX's earliest popular applications was in the [[Palm Pilot|Palm III]]. This [[personal digital assistant|PDA]] and its many successors use OBEX to exchange business cards, data, even applications.

Although OBEX was initially designed for infrared, it has now been adopted by [[Bluetooth]], and is also used over [[RS-232]], [[USB]], [[Wireless Application Protocol|WAP]] and in devices such as [[Livescribe]] smartpens.
