Description

Technical Field

[0001] The present invention relates to a fraud prevention method for purchasing and recharging a virtual point card, and in particular to a fraud prevention method for recharging points applicable to a code scanning device. Background Art

[0002] Existing point top-up mechanisms typically involve consumers purchasing a top-up card from a convenience store and then entering the card serial number to top up their game account. This method lacks security and effectiveness, and can lead to fraud rings exploiting consumers to launder money through point purchases.

[0003] Fraud rings using convenience stores to defraud game points are extremely difficult to prevent. One scam among gamers exploits loopholes in existing top-up methods, using online social networks and messaging apps to defraud players of their point card serial numbers, top-up passwords, mobile phone numbers, and any SMS passwords (authentication codes). Once points are directly deposited, players are unable to obtain a refund from the original store by the time they realize they've been scammed.

[0004] Therefore, designing a point recharge risk management mechanism is an urgent issue for recharge card issuers. Summary of the Invention

[0005] In view of this, the present invention provides a point recharge anti-fraud method suitable for a code scanning device, which can ensure that the game application that initiates the recharge request is consistent with the game application at the time of recharge, or that the mobile phone where the game application that initiates the recharge request is located is consistent with the mobile phone at the time of recharge.

[0006] The present invention provides a point recharge anti-fraud method applicable to a code scanning device. It is an anti-fraud method for players to recharge using a mobile phone game application. The method comprises: the mobile phone sends a recharge request initiated by the player on the recharge page of the game application to a recharge server, the recharge request including the mobile phone number, the game application, the publisher, and a recharge point and a convenience store entered by the player on the recharge page; the recharge server extracts a convenience store POS barcode generation method stored in a database according to the convenience store in the recharge request, generates a recharge barcode from the game application (information) and the recharge points according to the convenience store POS barcode generation method, binds the recharge barcode to the recharge request and stores it as a purchase order. The purchase record is stored in the database, and the recharge barcode is sent back to the recharge page for display. The convenience store's barcode scanner reads the recharge barcode, collects the payment fee, and notifies the convenience store server to send a cancellation notice to the recharge server, which includes the recharge barcode. The recharge server receives the cancellation notice, extracts the recharge request corresponding to the recharge barcode in the purchase record in the cancellation notice from the database, and sends a cancellation notice to the application server based on the issuer specified in the recharge request. The cancellation notice includes the recharge points, mobile phone number, and game application. The application server receives the cancellation notice and tops up the recharge points according to the game application installed on the mobile phone with the mobile phone number specified in the cancellation notice, completing the recharge operation.

[0007] For example, a new player joins a guild. Due to their interest in the game and the guild's need to maintain a stable ranking, they need to accelerate their character's level. They set a goal of reaching level 50 within a week, so they request 5,000 points (equivalent to NT$5,000) on the game's official top-up platform. Since Convenience Store A is located downstairs, they choose the convenience store's real-time deposit payment method. Player A obtains a QR code for Convenience Store A payment on the top-up page and proceeds to Convenience Store A to scan and redeem their payment. Approximately five minutes after redemption, the game receives a point credit notification. Using these 5,000 points, the player successfully reaches level 50 within a week, completing the in-game guild's basic requirements and enjoying the game's entertainment experience.
