Coin counting implementation device based on SE chip and JavaCard

The invention relates to the technical field of digital transactions, in particular to a coin counting implementation device based on an SE chip and JavaCard, which comprises terminal equipment, a payer hardware wallet and a payee hardware wallet. The terminal equipment establishes connection with the hardware wallets of the collector and the payer when performing the double offline transaction; the hardware wallets of the collector and the payer sequentially generate and exchange initialization instructions; after the information verification is correct, the payer hardware wallet updates the currency string owner which does not perform the offline payment transaction to a payee; and the hardware wallets of the two parties finally generate a transaction flow through a series of interactions. It can be understood that according to the technical scheme provided by the invention, each off-line coin string only supports one off-line payment transaction, and when the validity period of the off-line transaction is
