    • Systems and methods are disclosed to provide an animated 2D barcode check that is used to securely and efficiently transmit financial information between mobile devices. The financial information includes a check written by a payer and transmitted to a merchant. The check includes account information of the payer and of the merchant with a payment service provider, a payment amount, and a cryptographic signature that has been certified by the payment service provider. The payer's mobile device encodes the check into a sequence of 2D barcodes and displays the sequence of 2D barcodes in a loop that is scanned by a camera on the merchant's mobile device. The merchant uses the cryptographic signature to verify the validity of the signature on the check without having Internet connectivity to the payment service provider. The merchant may later present the check to the payment service provider to receive payment.
    • 公开了系统和方法来提供用于在移动设备之间安全且有效地传送财务信息的动画2D条形码检查。 财务信息包括由付款人书写并发送给商家的支票。 检查包括付款人和具有支付服务提供商的商家的帐户信息,支付金额和已由支付服务提供商认证的加密签名。 付款人的移动设备将支票编码成二维条形码序列,并在由商家移动设备上的相机扫描的循环中显示二维条形码序列。 商家使用加密签名来验证支票上的签名的有效性,而无需与支付服务提供商互联网连接。 商家可以稍后将支票提交给支付服务提供商以接收付款。
