Abstract

A method of conducting an offline virtual currency transaction is disclosed. The method may include steps of generating one or more virtual wallets; depositing certain amount of virtual currency in said virtual wallets; a payer transmitting at least a portion of said virtual currency to a payee through an offline platform; and payee confirming reception of the virtual currency. In one embodiment, the step of transmitting at least a portion of said virtual currency to another user through an offline platform may include a step of scanning a QR (Quick Response) code to transmit the virtual currency. In another embodiment, the virtual currency can also be transmitted through infrared. In a further embodiment, the step of confirming reception of the virtual currency may include a step of said payee deleting private key.

Claims
