TAG, was created in 1978 with an exclusive and select number of Diebold customers. TAG's original purpose was to serve as a beta test group for Diebold's first automated teller machines (ATMs). TAG has since developed into a thriving and energetic independent user group encompassing financial institutions and ATM deployers of all sizes.

TAG has consistently adapted to fit the expanded knowledge and changing needs of the TAG membership and looks forward to helping build new, profitable relationships among its members.
