36 CFR Part 1194 - Proposed Information and Communication Technology (ICT) Standards and Guidelines NPRM

Advisory 402.1 General. Self-service machines, information kiosks, set-top boxes, and devices like most copiers, fax machines, and calculators have closed functionality because, by design, these products preclude the user from adding peripherals or software. ICT also may have closed functionality in practice even though the manufacturer did not design or develop it to be closed. Computers with security restrictions that prevent end users from adjusting settings or adding assistive technology have closed functionality.
