    Abstract: Computer-implemented methods, systems and devices facilitating the methods, and computer-readable medium storing computer readable code, which, when executed, performs the methods are provided for coupon verification. The methods include receiving from a coupon verification terminal via a mobile network a verification data package based on at least an additional verification information and a verification code of a coupon, verifying whether or not the coupon is valid and has not been redeemed, and sending the verification result via the mobile network to the coupon verification terminal. The coupon verification terminal comprises an input module, a CPU configured to provide the additional verification information and to generate the verification data package by encrypting the additional verification information and the verification code, and a mobile communication module configured to, via a mobile network, send the verification data package to a verification server and receive a verification result from the verification server.

    Abstract: Computer-implemented methods, systems and devices facilitating the methods, and computer-readable medium storing computer readable code, which, when executed, performs the methods are provided for offline coupon verification. The methods may include inputting a verification code of a coupon to a coupon verification terminal, decrypting the verification code using a terminal private key to obtain a merchant ciphertext, decrypting the merchant ciphertext using a merchant-specific server public key to obtain a purchase information corresponding to the coupon, comparing the purchase information with a database to determine whether the purchase information is correct, displaying a negative verification result if the purchase information is not correct, and displaying a positive verification result if the purchase information is correct and the coupon has not been previously consumed, registering the coupon as consumed in the database for future verifications, when or after the coupon been verified, and synchronizing the database with that of a server.

    Abstract translation: 计算机实现的方法，便于该方法的系统和设备以及存储计算机可读代码的计算机可读介质，其被执行时执行该方法被提供用于离线优惠券验证。 所述方法可以包括将优惠券的验证码输入到优惠券验证终端，使用终端专用密钥解密验证码以获得商户密文，使用商家特定服务器公钥解密商家密文以获得对应的购买信息 对于优惠券，将购买信息与数据库进行比较以确定购买信息是否正确，如果购买信息不正确则显示否定的验证结果，并且如果购买信息是正确的并且优惠券没有，则显示肯定的验证结果 已经被消费，注册在数据库中消耗的优惠券用于将来的验证，在优惠券被验证之后或之后，以及将数据库与服务器的数据库同步。
