For the advantage that makes technical solution of the present invention is clearer, the present invention is elaborated below in conjunction with drawings and Examples.
Embodiment one
Present embodiment provides a kind of extended method of many wallets, and as shown in Figure 1, the extended method of described many wallets comprises:
101, set up at least two stored value card files in smart card, each stored value card file is provided with unique stored value card file identification;
In the present embodiment, under same application, establish 16 stored value card files, as shown in Figure 2, the stored value card file identification that different stored value card files is corresponding different, each e-file sign comprises the sexadecimal number of two bytes.
102, the form to smart card transaction initiation message to be received is provided with, and preservation is provided with the result in smart card.
Particularly, described form setting to smart card transaction initiation message to be received comprises: the form of circle being deposited the transaction initiation message is provided with and the form of consuming the transaction initiation message is provided with.
(1) form that circle is deposited the transaction initiation message is provided with.
As shown in Figure 3, the formatting of circle being deposited the transaction initiation message is for comprising parameters C LA, INS, P1, P2, Lc, DATA and Le, and CLA, INS, P1, P2 are the command header of four fixing bytes, and Lc, DATA and Le are adjustable length command body; Wherein, CLA is the classification byte of command message, INS is the command byte of command message, P1 is the transaction initiation type identification, P2 is a stored value card sign, and Lc is the physical length in the terminal device order data territory of sending, and DATA is a data field, comprise key identifier, dealing money, Terminal Equipment Identifier, Le is the greatest hope length of response data; Wherein, CLA, INS, P1, Lc and Le are constant, and P2, DATA are variable.：
Because 16 wallets are supported in described application, when the transmission circle is deposited the transaction initiation message, utilize the value of P2 to distinguish different wallets, P2=0xX2, X is the numerical value of 0-F, refers to which wallet is concluded the business.
(2) form to consumption transaction initiation message is provided with.
As shown in Figure 4, for comprising parameters C LA, INS, P1, P2, Lc, DATA and Le, CLA, INS, P1, P2 are the command header of four fixing bytes with the formatting of consumer sale Initial message, and Lc, DATA and Le are adjustable length command body; Wherein, CLA is the classification byte of command message, INS is the command byte of command message, P1 is the transaction initiation type identification, P2 is a stored value card sign, and Lc is the physical length in the terminal order data territory of sending, and DATA is a data field, comprise key identifier, dealing money, Terminal Equipment Identifier, Le is the greatest hope length of response data; Wherein, CLA, INS, P1, Lc and Le are constant, and P2, DATA are variable.
Because 16 wallets are supported in described application, when sending the consumer sale Initial message, utilize the value of P2 to distinguish different wallets, P2=0xX2, X is the numerical value of 0-F, refers to which wallet is concluded the business.
