Windcave Limited 33 Wilkinson Road, Ellerslie Auckland 1060 New Zealand 21 February 2022 Federal Communications Commission Equipment Authorisation Branch 7435 Oakland Mills Road Columbia, MD21046 United States of America Subject: Third Party Confidentiality Request for Exhibits under FCC ID: 2AC2O-SCR200MO-B To Whom It May Concern: Pursuant of Section 0.457 and 0.459 of the Commission’s Rules and KDB 726920 D01 Confidentiality Request Procedures, we hereby request that the exhibits listed below, submitted in support of the certification application for FCC ID: 2AC2O- SCR200MO-B, be withheld permanently from public disclosure: • Schematics • Block Diagram • Operational Description • Internal Photographs • Hardware Guide The above exhibits, owned solely by Windcave Limited, contain trade secrets and proprietary information which is not routinely available to the public or to our competitors. The public disclosure of these materials may be harmful to the applicant and provide unjustified benefits to its competitors. Confidentiality of the internal photographs is specifically sought because the device could be re- engineered from the photographs. Windcave Limited 33 Wilkinson Road, Ellerslie Auckland 1060 New Zealand Windcave controls information about and access to the device as follows: • The schematics, internal photographs and the like are only used internally by Windcave or by those 3 rd parties as are required to complete product testing. • User manuals do not include schematics, internal photographs, detailed descriptions of device operation or detailed block diagrams. • To meet strict Payment Card Industry (www.pcisecuritystandards.org) security requirements, the devices include security mechanisms which disable the device if it is opened and prevent the modification of the firmware by the user. • The PCI Security Standards require that all devices are returned to Windcave Ltd. at their end of life. Therefore Section 7.6 of the Windcave Customer Contract states: “Consequences of termination: On the termination of this Agreement, you must immediately: a) return all Windcave Limited Products to Windcave Limited...” The applicant understands that pursuant to Section 0.457 of the Rules, disclosure of this application and all accompanying documentation will not be made before the date of the Grant for this application.

CLIENT INFORMATION Company Name Windcave Ltd Address 33 Wilkinson Rd, Ellerslie State Auckland 1060 Country New Zealand Contact Cameron Collard ____________________________________________________________________________________________________________________________________________________________________________ Page 5 of 27 Test Report No 211013.4 24 th December 2021 This report may not be reproduced except in full. 5. DESCRIPTION OF TEST SAMPLE Brand Name Windcave Model Number SCR200MO Product Secure Card Reader (NFC only) Manufacturer Windcave Limited Country of Origin New Zealand Serial Number(s) NFC sample: 2421400050 NFC dummy load sample: 2421400051 Release Version B FCC ID 2AC2O-SCR200MO-B The device tested is a Near Field Contactless Secure Card Reader (NFC Card Reader) that operates on 13.560 MHz. The device contains no other transmitting certified modules. Testing was carried out when the device under test was attached to a laptop computer using a USB to UART converter that was attached to the USB port on the laptop computer. The UART convertor was attached to the device using a 1 metre length of Ethernet cable with the UART converter powering the device under test. The client has declared the highest frequency in use in the device is 108 MHz. Testing was carried out using a laptop computer that used Windcave test software to exercise the test sample where the NFC transmitter was operating with the signal being modulated. Testing was carried out to determine the effects of a change to the NFC contacless standard (EMV Contactless v3) which has required an update to the NFC front end integrated circuit. No other changes have been made to the device that was originally certified. ____________________________________________________________________________________________________________________________________________________________________________ Page 6 of 27 Test Report No 211013.4 24 th December 2021 This report may not be reproduced except in full. 6.
