Redeem your gift cards at any of our Merchants
You can purchase a gift card from any of these locations
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 test BIN number is the first six to eight digits of a card number used in a sandbox. Payment processors publish these digits next to test card numbers. The numbers work against test endpoints for that processor and nowhere else.
The BIN is the leading segment of the primary account number. Under ISO/IEC 7812 the issuer identification number runs eight digits. Most systems read six. The digits identify the issuing bank, the card network, the card type and the country of issue. A BIN holds no cardholder name, no expiry date and no CVV.
Processors and gateways publish test card numbers in developer docs. Stripe lists numbers for Visa, Mastercard and American Express with fixed BINs such as 4242. Adyen, PayPal and Authorize.net do the same. Each number triggers a set response: approve, decline or a specific error code. Test BINs are documented data, not secrets.
Test BINs fail against live endpoints. A live authorization checks the full account number, the expiry date and the CVV against the issuer. A test BIN alone passes no check.
Live BIN tables from Visa and Mastercard are licensed data. Access requires a contract with the network or a provider. Public BIN lookup sites show partial ranges, and those ranges go stale as issuers reissue portfolios.
Guessing live card numbers from a BIN is card fraud in the US under 18 U.S.C. 1029 and carries prison terms. PCI DSS sets rules for storage of account data for merchants that handle live cards. Sandbox test data sits outside that scope because it maps to no real account.
