  2. This Offer is only applicable to a cardholder holding a valid Mastercard consumer card issued in Hong Kong (“Eligible Mastercard”). A cardholder holding an Eligible Mastercard shall be referred to as the "Cardholder" below. An “Eligible Transaction” occurs when a Cardholder makes a transaction through KeyChain Pay mobile application and uses his/her Eligible Mastercard to pay for all relevant fares and fees associated with that transaction during the Promotion Partnership Period.
  3. This Offer is applicable to legitimate tenancy agreement originated and issued in Hong Kong only. Cardholders must pay the rent (including deposit or disbursement if applicable) at KeyChain Pay mobile app and settle the payment with an Eligible Mastercard in Hong Kong dollars. Individual landlord or tenant (Cardholder) will enjoy 2.2% special transaction fee offer. The Offer is not applicable to payment of rent through any payment channel other than KeyChain Pay (eg with other channels like cash, cheque or transfer). Failure of payment by Eligible Mastercard will result in revoking of transaction fee discount up to 0.7% by charging original fee at 2.9%.
  4. Once the recurring payment is authorized with an Eligible Mastercard to enjoy the Offer, Cardholder (tenant) is only allowed to change to another Eligible Mastercard from the prior authorized Mastercard during the period of Smart Contract.
  5. Cardholders are required to provide their own valid Eligible Mastercard upon registration in KeyChain Pay mobile app in order to be eligible for the Offer.
  6. Unless otherwise specified, the Offer cannot be used in conjunction with any other offers available during the Promotional Period.
  7. If the Cardholder requests refund or partial refund, that relevant transaction will not be eligible for the Offer.
  8. Any fraud and/or abuse of the Offer by any person (as determined by the KeyChain Pay and Mastercard Asia/Pacific (Hong Kong) Limited at their sole discretion) will result in forfeiture of the person’s eligibility to the Offer as well as cancellation of the Cardholder's Smart Contract(s). KeyChain Pay and Mastercard Asia/Pacific (Hong Kong) Limited reserve the right to deduct the value of any Offer redeemed inappropriately to a Cardholder directly from any of the Cardholder’s Eligible Mastercard without prior notice and/or take legal action in such instances to recover any outstanding amounts.
  9. The Offer is only applicable to Cardholders whose Eligible Mastercard accounts are determined at the sole discretion of the card issuing bank to be in good standing and remain valid and not in default during the relevant Promotional Period.
  10. Terms and conditions from KeyChain Pay shall apply to the Offer. Cardholders shall check the KeyChain Pay website for details.
  11. This Offer is subject to the terms and conditions mentioned herein. Mastercard Asia/Pacific (Hong Kong) Limited and/or KeyChain Pay reserve the right to amend these terms and conditions and to terminate the Offer at any time without prior notice to the Cardholders. Mastercard Asia/Pacific (Hong Kong) Limited and/or KeyChain Pay accept no liability for any such change or termination of the Offer or the Offer related Terms and Conditions. The Offer above cannot be exchanged for cash/service, other products or discounts and is not transferable.
  12. In the event of disputes, the decision of KeyChain Pay and Mastercard Asia/Pacific (Hong Kong) Limited shall be final and binding. These terms and conditions are governed by and will be construed in accordance with the laws of the Hong Kong Special Administrative Region.
  13. Should there be any discrepancy or inconsistency between the English and Chinese versions of these Terms and Conditions, the English version shall prevail.
