In the embodiment of the present application, based on embodiment described in Fig. 1, Fig. 2 or Fig. 3, step 101 obtains the transaction letter that businessman uploads
Breath after the Transaction Information is registered in block catenary system simultaneously the whole network broadcast, can also will specifically be refunded by block chain
The amount of money is detained in advance in the form transferred accounts, it is subsequent be confirmed as user and refund when, then moved back for user by block catenary system
Tax.Below referring to Fig. 4, based on embodiment described in Fig. 1, Fig. 2 or Fig. 3, step 101 obtains the Transaction Information that businessman uploads, will
The Transaction Information is registered in block catenary system and after the whole network broadcast, a kind of in the embodiment of the present application to be based on block chain technology
Another embodiment of overseas TAX FREE SHOPPING method include:
401 receive transferring accounts for the businessman by stored value card；
In the present embodiment, transferring accounts for the businessman is received by stored value card, the number transferred accounts includes the refund
The amount of money.
Wherein, using the characteristic that can not be distorted of data in block catenary system, receive what businessman sent by stored value card
It transfers accounts, the specific number transferred accounts includes therefore the refund amount of money is according to the Transaction Information described in subsequent step 105
It includes: that block chain node device transfers accounts the refund amount of money to the user that the user, which carries out refund, to complete to refund
Process.
In the embodiment of the present application, specifically in practical application, the publicly-owned platform chain of block chain can be run, platform can be with
A digital wallet is distributed for the user of each registration.Firstly, businessman user purchases this after consumer-user does shopping in overseas
The identification code of the Transaction Information of shopping is written in block platform chain by triggering one intelligent contract for the direct cochain of object process,
Then payment flow is completed, which can realize by intelligent contract divides account automatically, and the after-tax amount of money enters directly into businessman
Digital wallet, and refund amount of money part enter an intermediate account.After this, there are a self-help type machine, it is
One has the block chain evidence obtaining server of verifying node, which is capable of the two dimensional code of items scanning and the two dimensional code of air ticket
And complete associated verification.The intelligence contract can also set an execution condition, i.e., in defined time limit, user is reached
Airport, (the block chain evidence obtaining server with verifying nodal function) passes through the two dimension of items scanning on defined self-help machine
Code, verifying node will realize that evidence obtaining process (confirms user by commodity band by two dimensional code item identification code obtained on chain
Departure).Once evidence obtaining is errorless, then consumer-user then scans the air ticket of oneself, and verifying node obtains long-range after ticket information
Flight Information server is called, confirms that the air ticket of user is errorless.After the completion of above procedure, then contract executes automatically, by intermediate account
The amount of money in family is transferred in the digital wallet of user, completes entire refund process.
