ISO 18443:2016

ISO 18443:2016 Practice defines extensions to the SLE API in terms of: a) the RCF-specific functionality provided by API components; b) the RCF-specific interfaces provided by API components; and c) the externally visible behavior associated with the RCF interfaces exported by the components. It does not specify: a) individual implementations or products; b) the internal design of the components; and c) the technology used for communications. ISO 18443:2016 defines only interfaces and behavior that must be provided by implementations supporting the Return Channel Frames service in addition to the specification in reference [3].
