Accompanying drawing explanation
Fig. 1 opens method flow diagram according to the invoice based on Android system and VPDN of the present invention's specific embodiment.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly thorough, below in conjunction with drawings and Examples, method being opened to the invoice based on Android system and VPDN of the present invention and is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The hardware that the present invention needs is exactly the terminal device and the wireless printer that run Android system, terminal device is connected to VPDN private network, then invoice issuing is carried out, data upload, the related service operations such as invoice inquiry, and connected printing invoice by bluetooth, client and merchandise news maintenance etc.
The invoice that the present invention is based on Android system and VPDN opens method, as shown in Figure 1, comprises the steps:
Step S100, carries out network connection, and signs in VPDN private network;
VPDN adopts Virtual tunneling and re-authentication means, a set of safe VPN (virtual private network) has been constructed in the open internet that still there is potential safety hazard, private network and public network has been kept apart, thus ensure that the security of transmitted data on network.
First guarantee that terminal device can access public network, because VPDN network is based upon on public network.
Android system supports multiple VPDN protocol type, if successfully connect VPDN server, signs in private network, needs to use the protocol type identical with VPDN server.
Operator's end generally all supports L2TP agreement, and what have also supports the L2TP/IPSEC PSK that safe coefficient is higher or IPSECXAUTH PSK.
After being successfully logged onto VPDN private network, just can have access to the billing server be placed in private network, can the mutual of follow-up business datum be carried out.
Step S200, is carried out bluetooth connection, handheld device is connected by Bluetooth protocol with printer;
Want the printing realizing invoice with handheld terminal, blue-tooth printer or WIFI printer can be used.General employing blue-tooth printer can satisfy the demands, and it is more universal simultaneously, and price is also cheaper.As long as handheld device be connected by Bluetooth protocol with printer, the form that just invoice data can be accepted according to printer, is sent in printer from handheld device, and then prints on paper invoice.
