The Natural Security standard defines the architecture and different components required to enable a transaction based on a wireless acceptance device (WAD) used by a vendor or service provider (e.g. a merchant) and a wireless personal device (WPD) used by an individual user. The Natural Security standard defines the following core specifications:
- The Natural Security General Description [CORE1 / V 2.3] provides an introduction and a general overview of the Natural Security technology. It also describes services that can be provided by Natural Security technology.
- The Wireless Personal Device (WPD) [CORE2 / V 2.4] specification describes the device used by the Individual User (e.g. a customer) to execute a WPD session. This document also describes the Personal Access Provider architecture, which is the Natural Security core application residing in any WPD.
- The Wireless Acceptance Device (WAD) [CORE3/ V 2.4] specification describes the device used by the Acceptance User (e.g. a merchant) to execute a WPD session. This document also describes the transaction flow of a WPD session.
- The Wireless Personal Area Network (WPAN) [CORE4/ V 3.02] specification describes a mid-range wireless communication protocol used to connect the WPD with the WAD. This protocol based on WPAN is defined by Natural Security.
- The Wireless Biometric Intelligent Reader (WBIR) Protocol [CORE5 / v2-43] specification provides the functional description of a device integrating the principal Natural Security components, thus simplifying integration of the Natural Security solution in existing systems. This document also describes the protocol messages to be used by a “Controlling-Device”, such as a POS or a PC, to control a WBIR.
