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 test data generator built for sandbox payment testing, not a service that claims to supply live card verification values. A legitimate tool creates synthetic primary account numbers that pass a Luhn check, matching expiry dates, and CVV or CVC strings in the correct 3 or 4 digit format so your checkout, risk, and settlement code can be exercised end to end. Real CVV values cannot be bought or stored after authorization, so a vendor that offers them is either committing fraud or reselling stolen data. The purchase decision itself comes down to sandbox coverage, seed control, framework fit, and data governance.
These tools sit next to your payment integration and produce the inputs your test suite needs. The useful ones go past random numbers and map each generated record to a known processor response.
Vendors define capacity in different ways, so ask for these numbers in writing and test them during a trial.
No. Card verification values belong to the cardholder and the issuing bank. There is no lawful marketplace for them, and offers to sell them are fraud.
You can, but you should not. Processor sandboxes provide documented test numbers and matching verification values that behave the same way without exposing a real account.
No. The generator supplies inputs; the sandbox supplies responses. You want both, and the better tools connect them.
Keep it in test environments, use synthetic data only, and confirm the vendor does not persist verification values. Data that never touches a live authorization stays out of scope.
Spend your budget on sandbox integration and deterministic test data, not on anything promising real card details. Run a trial against your own CI pipeline, generate a few hundred cases, and check whether the same seed reproduces the same failures. If it does, and the edge case library covers your decline and authentication paths, you have found a tool worth buying.
