The subject matter of this paper is to provide information security for an authorized data within the access control systems using encryption technique in QR-code technology. The research goal was investigation of providing secure access control systems using cryptosystem based on RSA algorithm and pseudorandom number generator. The task was to develop an application encrypting information to provide information security for access control systems using encryption techniques in QR-code technology. The following results were obtained: main characteristics of access control system built on QR-code technology have been described; advantages of this technology have been investigated and also have been compared with the other access control systems; software application encrypting QR-codes for an authorized access has been created.
