This Notice explains how Nano Advanced Services Limited (“NAS”, “we”, “us”) uses electronic communications and electronic signatures with our Partners and prospective Partners, and the legal basis on which we do so. It applies in connection with the NAS Partner Platform Terms, the Data Processing Addendum, any Program Order, and any other agreement, notice, disclosure, or record we exchange with you (collectively, the “Communications”).
This Notice is issued under (and is intended to be read consistently with) the Hong Kong Electronic Transactions Ordinance (Cap. 553) (the “ETO”), Regulation (EU) No 910/2014 (eIDAS), the UK Electronic Communications Act 2000, the UK Electronic Identification and Trust Services for Electronic Transactions Regulations 2016, the U.S. Electronic Signatures in Global and National Commerce Act (15 U.S.C. §§ 7001–7031) (“ESIGN”) and the Uniform Electronic Transactions Act (“UETA”) as adopted by the relevant state, and equivalent legislation in other jurisdictions where applicable.
In the United States, electronic records and electronic signatures are given legal effect under ESIGN and UETA as adopted by the relevant state, and an electronic record or signature is not denied legal effect solely because it is in electronic form. This Notice is provided in the context of business-to-business agreements with the Partner, to which the consumer-consent provisions of ESIGN (15 U.S.C. § 7001(c)) do not apply.
1. Your consent to electronic communications
By accepting the NAS Partner Platform Terms, signing a Program Order, registering for a Partner Account, or otherwise engaging with us, you consent to:
- Receiving Communications from us in electronic form, including by email, in-platform notification, web-portal posting (in the Business Portal, Support Portal, or Admin Back-office), webhook, or other electronic channel we designate.
- Signing Communications electronically, where a signature is required.
- Receiving Communications in English, unless we and you agree otherwise in writing.
Your consent applies to all Communications between us, except where Applicable Law requires a paper or wet-ink form.
2. What we may send electronically
Electronic Communications may include:
- Contracts and amendments, including the Platform Terms, the DPA, any Program Order, and any addenda or schedules to the foregoing.
- Pre-contractual information, proposals, and quotes.
- Notices required under the Platform Terms or under Applicable Law, including notices of amendment, of suspension, of termination, of pricing change, of data-breach, of security incidents, or of regulatory change.
- Operational information about the Services, including release notes, deprecation notices, scheduled-maintenance notices, and incident updates.
- Account-administration items, including invoices, statements, reconciliation reports, OTP messages, password-reset emails, and access-management confirmations.
- Compliance and audit-related items, including questionnaires, audit findings, and corrective-action plan exchanges.
3. Electronic signatures we accept
For Communications that require your signature, we may accept any of the following, in our discretion (or in the form specifically required for a given Communication):
- A clickwrap acceptance (such as ticking an “I agree” box and clicking a button labelled to confirm acceptance).
- A typed name in a signature field, accompanied by an electronic record of who applied it and when.
- A scanned or pasted image of a handwritten signature.
- A signature applied through a third-party electronic-signature platform (such as DocuSign, Adobe Sign, HelloSign / Dropbox Sign, or equivalent).
- An eIDAS-qualified electronic signature, an eIDAS advanced electronic signature, or an electronic signature satisfying any equivalent or higher standard recognised under Applicable Law.
You confirm that you have authority to bind your organisation by applying any of the foregoing.
4. Legal effect
To the maximum extent permitted by Applicable Law (including Sections 5, 5A, 6 and 7 of the Hong Kong Electronic Transactions Ordinance, Article 25 of eIDAS, Section 7 of the UK Electronic Communications Act, and Sections 7001 and 7002 of ESIGN together with the corresponding provisions of UETA):
- An electronic record satisfies any legal requirement that information be in writing.
- An electronic signature satisfies any legal requirement that a document be signed.
- An electronic record is admissible in evidence and is not denied legal effect, validity, or enforceability solely on the ground that it is in electronic form.
These provisions do not apply to a limited category of documents excluded by Applicable Law (for example, wills and testaments, court orders, certain trust deeds, and certain other instruments). For any such document, we will agree a suitable execution method with you.
5. System requirements
To receive and act on electronic Communications, you need:
- An active email account at the address you provide to us.
- A modern web browser capable of accessing the Business Portal, the Support Portal, and the Admin Back-office over an HTTPS connection.
- The ability to view, save, and print PDF documents (and similar electronic formats).
- For some access flows, the ability to receive SMS or push-notification OTP codes.
You must keep your contact details current. We are not responsible for failed delivery caused by an out-of-date email address or by your spam filter blocking our messages.
6. Records and copies
We will keep electronic Communications in our records for the periods set out in our Privacy Policy and as required by Applicable Law. On reasonable written request, we will provide you with a copy of any electronic Communication we have sent to you, in an electronic format (or, where you request and we agree, in paper form). Reasonable copy-fees may apply for non-routine requests.
You should retain your own copies of Communications, especially those relating to contractual commitments, payments, and notices.
7. Withdrawing consent
You may withdraw your consent to receive Communications electronically at any time by writing to legal@nas.cards. We will acknowledge the withdrawal within five (5) business days.
Withdrawing consent has the following consequences:
- We may not be able to provide the Services in the same way, because many parts of the Services depend on electronic Communications.
- We may, on reasonable notice, terminate the Platform Terms with you in accordance with their termination provisions, where we determine that we cannot continue to provide the Services without your electronic consent.
- Withdrawal does not affect the legal validity of any Communication exchanged before withdrawal.
