    • A first command is sent from a payment terminal assembly to a payment device with an on-device balance to compute a cryptogram to complete a putative transaction. It is detected that the cryptogram is not received as expected. In response, an identifier of the payment device and transaction recovery data associated with the putative transaction are stored in a storage area of a terminal memory of the payment terminal assembly. The payment terminal assembly obtains the identifier of the payment device, upon re-presentation of the payment device. Upon such re-presentation, the payment terminal assembly compares the obtained identifier of the payment device to contents of the storage area. Conditioned at least upon the comparing yielding a match, a second command is sent from the payment terminal assembly to the payment device to instruct the payment device to re-produce the cryptogram to complete the putative transaction.
    • 第一命令从支付终端组件发送到具有设备上余额的支付设备,以计算密码以完成推定的交易。 检测到没有按预期方式收到密码。 作为响应,将与推定交易相关联的支付设备和交易恢复数据的标识符存储在支付终端组件的终端存储器的存储区域中。 支付终端组件在重新呈现支付设备时获得支付设备的标识符。 在这种重新呈现时,支付终端组件将获得的支付设备的标识符与存储区域的内容进行比较。 至少在进行比较的条件下产生匹配时,第二命令从支付终端组件发送到支付设备,以指示支付设备重新产生密码以完成推定的交易。
