This paper describes a group of technology for automatic data acquisition in construction, which is referred as keyless data acquisition(KDA) technology, including bar coding, magnetic strip, optical character recognition, radio frequency identification and voice recognition. First, past literature related to this area is reviewed and briefly discussed. Then KDA implementation scheme is presented, detailing the considerations and logical steps involved in this issue. The make this concept better understood, a brief KDA implementation example in material control with special emphasis on warehousing id depicted. Finally concluding remarks and future research directions are given. The experience gained from field tests reveals that the group of KDA technology in combination gives excellent solutions to field data collections/ entry problem, whereas a stand alone technology such as bar coding, is insufficient for particular use.
