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.
Card testing is a run of small authorization attempts against your payment form using card numbers the attacker did not get from you. The ones that go through are the live numbers. Chargebacks follow weeks later, almost always as fraud disputes, and they land on you even though the person disputing never intended to buy from you at all.
A test charge is small. I've seen them land between 50 cents and three dollars, sometimes a dollar donation form, sometimes a digital trial signup. The attacker is not buying anything. They want a yes or no from the issuer. So the order looks ordinary on the surface: card number, expiry, CVV, maybe a ZIP code. Once a number works, it gets sold or spent somewhere else for a larger hit.
The chargeback arrives because the real cardholder sees the line item on a statement and calls it fraud. They are right. Under card network rules, an unauthorized transaction is a valid dispute no matter how small it was. You lose the amount, the processing fee, and often a chargeback fee on top. A batch of 200 test charges that all get disputed costs more than most merchants make in a week.
Turn on CVV and AVS requirements if you switched them off for conversion. Require them for the first order from a new customer, then relax.
Set velocity limits per IP, device, email, and card BIN. A cap of three attempts per hour per device kills most scripts before they land a working number.
Add 3-D Secure for high-risk segments. It shifts liability for fraud chargebacks and makes automated testing expensive because the issuing bank is in the loop.
Put a CAPTCHA or a challenge step on checkout for flagged sessions. Cheap bots fold. Better bots cost the attacker more than the test is worth.
Watch your authorization rate by BIN. If one issuer's approval rate drops from 80 percent to 20 percent inside an hour, that is a test run, not a marketing problem.
Set a minimum transaction amount, or require an extra verification step for anything under a few dollars if your business does not normally sell at that price.
Refund the test charges yourself before they become disputes. It is cheaper than fighting, and it keeps your ratio clean. Then write down what you saw, tighten the rules that missed it, and contest anything that still lands if you hold evidence the order was authorized.
Keep an eye on the network monitoring programs. Visa and Mastercard both track fraud and dispute ratios, and a sustained card-testing problem can push you into a program with fines and a remediation plan. That is the real risk. The test charges are noise. The monitoring threshold is the part that hurts.
