By using the method, the terminal first reads the identifier information of the intelligent cryptographic device, and then utilizes the identifier information of the intelligent cryptographic device to obtain the user information corresponding to the intelligent cryptographic device, such that a customer makes payment without the use of a wallet, a credit card, a mobile phone or other methods, thus simplifying the interactive operation between the customer and a merchant, and improving user experience.
本发明提供一种数据安全交互方法和系统,其中所述方法包括:终端在信号覆盖范围内扫描智能密码设备,并获得扫描到的所述智能密码设备的标识信息;后台系统服务器获得所述智能密码设备的标识信息,并完成对所述智能密码设备的认证;在所述后台系统服务器完成对所述智能密码设备的认证之后,所述终端获取所述智能密码设备对应的用户信息;所述终端将所述用户信息存储到预先建立的当前用户列表中。 通过本方法,终端可以通过先读取智能密码设备的标识信息,再利用该智能密码设备的标识信息获取智能密码设备对应的用户信息。patents-wipo patents-wipo
