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.
AVS stands for Address Verification System. It compares the billing street number and ZIP code a buyer enters at checkout against the address the issuing bank has on file. CVV stands for Card Verification Value. It is a 3-digit code printed on the back of Visa, Mastercard, and Discover cards, and a 4-digit code printed on the front of American Express cards.
AVS compares numbers only. It does not compare the cardholder name. The issuer returns one letter per transaction.
AVS runs in the United States, Canada, and the United Kingdom. Issuers in other countries return U in many cases. Each merchant sets its own rules for which codes void a sale.
The issuer generates the CVV at card issue. The code is not encoded on the magnetic stripe and does not print on receipts. PCI DSS Requirement 3.2 bans storage of CVV data after a transaction is authorized.
A CVV result returns as M for match, N for no match, or U for not processed. A card with a mismatched CVV is declined. A missing CVV can pass on some card-not-present orders at the merchant's discretion.
Card networks do not expose AVS or CVV results to cardholders. Only the merchant's payment processor sees the response.
Payment gateways publish sandbox environments with test card numbers. Developers use those numbers to check decline logic, error handling, and checkout flow. A sandbox returns simulated codes. It does not contact an issuer and does not validate a real account.
No consumer tool can query the AVS or CVV status of a live card. Services that claim to do this are not connected to the card networks.
Using a card account without the cardholder's permission is access device fraud under 18 U.S.C. 1029. A first offense carries up to 15 years in prison and fines up to $250,000. Producing, selling, or transferring card numbers falls under the same statute.
Card data sold on forums is often stale, already canceled, or held by law enforcement. Buyers have no recourse.
