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.
Testing payment flows requires realistic card data without risking real accounts. Our credit card generator test tool creates fake, Luhn-valid numbers for sandbox environments. Quickly populate checkout forms, validate error handling, and train support teams—all without touching live cardholder data.
It is a utility that produces artificial card numbers that pass basic validation checks like the Luhn algorithm. These numbers are not linked to any real bank account or credit line, making them safe for development and QA.
The tool runs as a lightweight web app or CLI and supports JSON, CSV, and SQL output formats. It uses standard algorithms (Luhn, BIN lookup) to ensure numbers behave like real ones in validation logic. All generated data is clearly watermarked as test-only in metadata. No network connection or personal data is required.
Digital delivery is instant via email or dashboard download. Since this is a software product, we offer a 14-day satisfaction guarantee—if it doesn't fit your testing workflow, contact support for a refund. No physical shipping involved.
