By 'e-mail' is meant your official university email inbox, which was assigned to you upon enrollment. All messages regarding the production or validation of cards will be sent to this university email inbox. Therefore, please regularly check your email inbox! If you send us a message to the address karty (at) slu.cz, send it exclusively from your university email inbox. The purpose of this measure is to ensure your clear identification and secure email communication. The obligation of a student to use their university email inbox when communicating with the university arises from the Study and Examination Regulations.
