CONFIDENTIAL © ZigBee Alliance. All rights reserved. 2 Natural Security provides the first efficient and really easy-to- use three-factor authentication solution by enabling a consumer to conduct a transaction without manipulating its personal device or card The transaction is executed using a mid-range distance contactless interface combined with biometric authentication of the consumer The solution provides a unique user experience to authenticate for a wide range of services: – Physical or logical access control – Payment, Cash withdrawal – Secure access to Internet services Biometrics are securely stored in a secure element embedded in the consumer device providing increased privacy (no biometrics data stored remotely in data base, no PIN entering) Natural Security key features

Pilot implementation being launched in 2 locations in France Secured payment transaction using chip and PIN technologies – payment transaction executed in a few seconds – no card to manipulate, no PIN to enter First pilot in the world using 2 different biometric technologies (fingervein and fingerprint) in a real payment environment Pilot implementation: payment 4

CONFIDENTIAL © ZigBee Alliance. All rights reserved. NFC (not adopted) – Require the consumer to handle the device to execute a transaction which takes beyond the 3 sec. maximum transaction time – Does not provide a unique user experience for all types of transactions – Strong concern on the security and the confidentiality of the solution (data transmitted in clear between the merchant and the consumer devices) Bluetooth Smart (a.k.a. BTLE) (not adopted) – Modulation scheme susceptible to interference – NS-WPAN architecture challenging to implement – Latency variability too large for requirements IEEE 802.15.4 (adopted) – Native support for NS-WPAN architecture – Acceptable, predictable latency Technologies evaluated 11
CONFIDENTIAL © ZigBee Alliance. All rights reserved. Our WPAN implementation must respect several key requirements defined by government agencies such as : – Anonymous – No traceable protocol – Star topology (mesh topology cannot be used, introduces risk factors) – Fully reconfigurable, no coordinator And we add : – Dynamic and mobility – Mid range (between 1m to 3m) – High density of device – And low cost … Why do we need a « new » stack ? 12

Our stack will be implemented by several vendors Large organizations such as payment schemes will adopt this protocol only if it is owned and supported by an open association We conducted research to use other stacks or protocols (ZigBee pro, RF4CE, Dash7, Bluetooth) They don't meet our key business, technical and security requirements BLE could also be a potential good candidate however, 802.15.4 is considered as the best option at present Why do we need a « ZigBee » stack ? 16

Technical specification developed by natural security Test plan developed by UL (RFI Global) The stack has been implemented on several chips used by multiple vendors: Atmel TI ST (being currently tested) Strong, active support of large retailers and financial institutions Current situation 17
