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 card tester is any tool that checks whether a payment card number can complete a transaction. Payment processors ship sandbox test cards for developers, repair techs use bench testers on card readers, and criminals misuse the same idea to probe stolen card data. Two of those three are legal. The third is a federal crime.
Three groups use the phrase, and each one means something different. Context tells you which one you are looking at.
Processors publish fixed test numbers that trigger exact outcomes: approval, decline, insufficient funds, or a 3-D Secure challenge. A developer drops them into a staging checkout to confirm that error handling works. No real money moves, and the same numbers fail on live keys.
Test cards cover the cases that are hard to reproduce with real money. Expired cards, wrong CVV, soft declines, and region-specific currency behavior all have dedicated test numbers. Engineers run their payment tests against these instead of live cards, which keeps customer data out of test logs.
Field techs use a hardware card tester to isolate a fault before swapping parts. The device plugs into a card slot or SIM tray and reports whether the reader, the connector, or the firmware is the problem. Simple continuity testers cost $20 to $50, while multi-port diagnostic units run into the hundreds.
A separate category tests blank plastic: card thickness gauges and print alignment tools used by card bureaus and ID printers. These never touch a payment network.
Card testing is a fraud pattern where someone takes a batch of stolen card numbers and runs small charges to sort live accounts from dead ones. Numbers that authorize get sold again or used for larger purchases. The attacker needs only the number, the expiry date, and the CVV.
Merchants pay for the probes. Each one lands as an authorization request, and the successes turn into chargebacks. A single attack can push a small shop past card network dispute thresholds, which brings fees and possible account review.
This is why the search term sits in a gray zone. The same words describe a harmless developer utility and a tool for financial crime.
Processors also sell risk engines that score each authorization and hand back a fraud verdict in milliseconds. The card networks run attack intelligence programs that share compromised BIN ranges with acquirers, so a hit list often reaches the merchant before the attack does.
No. In the United States, using someone else's card number to run a transaction falls under 18 U.S.C. § 1029, the access device fraud statute. Penalties include fines and prison terms of up to 10 years for a first offense, with longer sentences for organized or repeat cases.
Buying stolen card data is a separate offense, and the market around it runs on scams. Sellers on messaging apps hand over lists that are dead, duplicated, or generated at random. A buyer has no recourse, because the deal itself is illegal and the seller knows the buyer cannot complain to anyone.
Yes. Both terms describe the same tools, and both cover sandbox utilities and fraud scripts. The label alone does not tell you which one you have.
Only if the issuer offers a balance endpoint. Retailer balance pages answer that question for cards you own. Sweeping numbers you do not own is fraud, even when the merchant is the issuer.
No. Sandbox numbers are tied to test keys and a test environment. They decline on production keys, and live numbers fail in sandbox mode.
Contact the acquirer, block the offending IPs and BINs, and review the successful authorizations before shipping anything. File a report with the FBI's Internet Crime Complaint Center if losses pass your chargeback threshold. Keep the logs, since disputes can arrive months later.
