The current legal status, as well as the historical perspective, allows us to assume that the EU legislator is not indifferent to the technological changes taking place. In order to ensure that the EU holds a leading position in the field of technology in various areas of citizens’ lives and the functioning of the economy, it must create an appropriate legal environment in this respect. Considering that the dynamics of change is felt in particular in the area of the financial market, whose potential for the development of innovative services and solutions is one of the highest, it should be emphasized that the regulation of this market is of great importance for ensuring that its participants can use new technologies in a way that stimulates market development, but also in accordance with EU values, in particular for the good of the individual and the public. It can therefore be argued that the innovativeness of the financial market becomes a normative assumption when creating acts of EU law and national financial market law, and also shapes a certain pattern thereof. This thesis will be subject to scientific reflection in the following study.

The subject of the authors' analyses in this article is the issue of requirements that must be met when publishing information recommending or suggesting an investment strategy in social media. The specificity of communication using technology that enables the exchange of various content via websites and mobile applications (e.g. social networking sites) creates special challenges for their users. This applies to both, the persons publishing, who must comply with the rules specified in the law (including those concerning counteracting unlawful behavior on financial markets) in order not to expose themselves to sanctions, as well as the recipients of the content, who may have difficulty recognizing the truthfulness of the information posted and be subject to information manipulation. This implies certain consequences for market confidence and investor protection. With this in mind, the study indicates and discusses the requirements that investment recommendations posted in social media must meet and the consequences of violating legally established obligations.

The purpose of this article is to analyze the law that regulates security measures when applying strong customer authentication (SCA). The rules introduced by PSD2 regarding identity identification when making payments through the use of SCA are to reduce the risk of fraud and increase payment security by introducing solutions that reduce the possibility of making unauthorised or fraudulent payment transactions. The significant impact of these provisions on consumers with the simultaneous complexity of the requirements makes it particularly important to undertake considerations aimed at conducting such analyzes and attempting to identify potential threats in connection with legislative interference in this area of payment services.

This article also draws attention to the phenomenon of technologization of the payment services market law, and more broadly the financial market.
