ISO/IEC 24727 (Identification cards – Integrated circuit card programming interfaces) is the first international standard to address the need for creation of a layered framework to support interoperability of smart cards providing identification, authentication, and (digital) signature services.
The standard is split into six parts:
- ISO/IEC 24727-1:2014 Part 1: Architecture
- ISO/IEC 24727-2:2008 Part 2: Generic card interface
- ISO/IEC 24727-3:2008 Part 3: Application interface
- ISO/IEC 24727-4:2008 Part 4: Application programming interface (API) administration
- ISO/IEC 24727-5:2011 Part 5: Testing procedures
- ISO/IEC 24727-6:2010 Part 6: Registration authority procedures for the authentication protocols for interoperability
Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
