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 BIN checker is a tool that looks up the first six to eight digits of a payment card (the bank identification number) to reveal the card's issuing bank, card type (credit or debit), and country of origin. Merchants use BIN checkers to screen transactions and reduce fraud risk. Criminals misuse the same data to test stolen card numbers before making unauthorized purchases.
A BIN checker maps the first digits of a card number to publicly available information about the issuing institution. It does not validate the full card number or authorize a transaction. The output typically includes the card brand, card level (e.g., classic, gold, platinum), and the issuing country.
Legitimate uses include routing transactions, applying correct interchange fees, and flagging high-risk cards. Fraud prevention teams use BIN data to spot mismatches between the card's origin and the customer's location.
Fraudsters use BIN checkers to test stolen card numbers in a process called card testing. They run small authorization attempts to see which numbers are valid before making larger fraudulent purchases. BIN data helps them match stolen numbers with plausible card types and issuers.
This activity often triggers multiple low-value transactions or repeated declines. Merchants should watch for patterns like many small orders from the same IP address or rapid-fire checkout attempts.
BIN checkers are one layer in a fraud prevention stack. Combine BIN data with address verification, CVV checks, velocity limits, and device fingerprinting. Flag transactions where the card's issuing country differs from the billing address or IP location.
Set rules to block cards from high-risk BIN ranges or prepaid card types if your business model allows. Review declined authorizations for card testing patterns and report suspicious activity to your payment processor.
Using a BIN checker for legitimate business purposes is legal. Accessing, buying, or selling stolen card data is illegal under laws such as the Computer Fraud and Abuse Act and the Identity Theft and Assumption Deterrence Act. Misusing BIN data to test stolen cards can lead to criminal charges and financial liability.
Merchants should keep records of fraud prevention efforts and ensure their BIN checking practices comply with payment network rules and data protection regulations.
