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 free CVV validator checks the shape of a number. It counts digits, confirms the field holds three or four characters, and runs a checksum. It does not contact a bank. It cannot tell you if a card is open, funded, or reported stolen. No web tool can return that answer without an authorization request sent from a merchant account.
The CVV is a 3-digit code printed on the back of Visa, Mastercard, and Discover cards. American Express prints a 4-digit code on the front and calls it the CID. The issuer generates the code when the card is produced. The code sits outside the card number, the magnetic stripe, and the chip.
Card networks use separate names for the same field: CVV2 at Visa, CVC2 at Mastercard, CID at American Express, CVV at Discover.
These steps run inside a browser. They finish in milliseconds. The result is a yes or no on format.
Authorization happens between a merchant, an acquirer, and the card issuer. The issuer checks account status, available credit, billing address, and the CVV on file. That answer comes back as an approval code or a decline. A public web page has no path into that system.
Any site that claims to check if a card is live is guessing, harvesting the numbers typed into it, or both. Card data entered on a random page goes to the page owner.
PCI DSS Requirement 3.2 bars storage of the CVV after authorization, even in encrypted form. A payment form passes the code to the processor and drops it. Logs, databases, and analytics tools must not capture it.
18 U.S.C. § 1029 covers access devices. It bars producing, selling, transferring, or possessing card numbers and CVV codes with intent to defraud. Penalties reach 10 years for a first offense and 15 years for repeat offenses, plus fines. Buying card data carries the same exposure as selling it.
Developers use format checks in checkout forms. Input masks and length rules cut typing errors. Test card numbers from networks and processors cover approved and declined paths in a sandbox. Those numbers come from the processor, not from a cardholder.
