A privacy apparatus (42) is installed on an existing ATM (12) to provide improved privacy for users of the machine. A frame (44) includes members (48, 56, 64) and extends externally of the ATM housing (14). A pair of disposed vertically extending panels (46) are attached in supporting connection with the frame. Each panel includes a generally horizontally extending shelf (76) which provides a support and writing surface. The privacy apparatus may be readily installed and removed without a requirement for producing fastener openings or other modifications to the existing ATM housing.
