Redeem your gift cards at any of our Merchants
Onyx Gift Cards is a Grenadian company designed to introduce, market and manage gift cards systems in Grenada for retailers and corporations. We are enthusiastic about the effect and influence we will have on the local market. We intend to expand our systems regionally with a range of product offerings and services.
Gift cards are the preferred way of giving and receiving gifts. They carry a monetary value that can be redeemed for gifts at your favorite store.
Onyx GiftCards are “Open Gift Cards” which means that they can be redeemed at multiple merchant locations. They are standard credit card size, can fit into the average wallet and made of PVC plastic. Onyx GiftCards are Barcoded for security and safety for the consumer and bear a disclaimer at the back.
Onyx Giftcards can be bought with a branded Card backer which is black in colour and is designed to fit the card. There is an area to write a brief message to the recipient as well.
A CVV test checkout is a transaction run in a payment processor's sandbox or test mode, where the gateway accepts a dummy card verification value instead of a real one. Test CVV values do not work on live checkout pages. Any processor that accepts a random CVV against a live card is either misconfigured or not a real processor.
The card verification value is a 3-digit code on the back of most cards (4 digits on American Express). In production, the issuing bank validates it. In a sandbox, no issuing bank is involved, so the processor substitutes a rule. Most gateways accept any 3-digit value, some accept only a fixed value, and some reject a specific value to simulate a failure.
Generated CVV lists, bought card data, and random numbers on live checkouts do not pass. Issuers decline them, processors log the attempts, and card testing traffic is a fraud signal that leads to account closure. Use test CVVs only against sandbox endpoints you control.
