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 fraud detection tool helps online merchants catch card-not-present fraud before an order ships. It validates the card verification value against the issuer response, layers in device and behavior signals, and routes suspicious orders to a review queue. Stores that run one usually see fewer chargebacks and far less manual review work.
The tool runs as a hosted service, so there is nothing to install on your own servers. You connect it through a REST API or a plugin for your e-commerce platform, run test transactions in a sandbox, then switch to live mode. Card data is encrypted in transit and at rest, and sensitive values are tokenized so raw numbers never sit in your database. Configuration covers rule thresholds, review queue assignments, and webhook endpoints, and every decision is logged for later audits.
Delivery is digital: your license key and onboarding guide arrive by email within minutes of purchase, and no physical shipment is involved. Active subscriptions include ongoing rule updates and access to technical support. If the tool does not fit your workflow, contact support inside the return window for a refund; nothing needs to be shipped back.
At checkout, the tool sends the CVV and address data to the payment processor and reads back the verification response. A mismatch raises the order's risk score and can trigger a hold or manual review before fulfillment.
Most merchants handle flagged orders with existing staff. Automated decisions clear the bulk of legitimate traffic, so reviewers only see the small share of orders that genuinely need a closer look.
It supports the major platforms through plugins and any custom checkout through the API. Setup is usually a matter of pasting API keys and choosing a rule preset that matches your risk appetite.
