The state-of-the-art methods for securing e-commerce transactions resistant even to compromised client workstation are based on using independent security devices or separate communication channels. These systems either do not support non-repudiation and/or are expensive and thus suitable only for special cases, where such additional costs are justified. In this article a new cheaper transaction verification method, which supports non-repudiation, is described. A cell phone or tablet communicating with the client workstation using qr-codes is used as an independent security device. There are no additional costs for service providers except for initial SW implementation. The proposed method brings better transaction verification to the areas where the usage of current methods is uneconomical.
