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.
Buy a card number test generator that works from published sandbox ranges, validates each number with the Luhn formula, and lets you pick the exact approval or decline outcome your checkout needs. Anything that claims to supply live card data is not a testing tool, and using it exposes your business to card network fines and criminal liability. The right purchase is small, documented, and boring.
A test generator builds card numbers that satisfy the format rules of ISO/IEC 7812 and the Luhn check digit, but belong to ranges the card networks and processors reserve for sandbox use. The number looks real to your payment form, so your validation, tokenization, and error handling paths get exercised without touching a real account. Most tools also emit the companion fields your form expects: expiry, CVV, cardholder name, and postal code.
Test BIN coverage of 5 to 20 ranges handles a single gateway. Plan on 30 to 100 ranges if you integrate two or more processors. A scenario library of 4 to 12 canned outcomes covers most checkout suites; above 20 matters mainly for subscriptions, partial captures, and 3DS flows. Throughput of 100 to 1,000 generated numbers per minute is sufficient for continuous integration. On retention, look for zero storage of pasted input or a documented purge window under 30 days.
No. Sandbox ranges are rejected by live processors. Using them in production only tells you that your test setup leaked into a release.
Often not. Processor documentation lists test numbers at no cost, and open libraries handle Luhn generation. Pay when you need bulk scenario fixtures, versioned exports, or a private deployment.
Yes, when every number comes from a published sandbox range and no real account is involved. Generating numbers from a real BIN to see if they work is a different act with different consequences.
Sandbox CVVs are fixed dummy values tied to specific test cards. They verify that your form passes the field through. They say nothing about a real card.
