FIELD: electrical engineering.
SUBSTANCE: device (2) comprises processor (20), memory card module (23) incorporating communication unit (233), transceiver unit (231), storage unit (232) including latent area (2322) and working area (2321). The latter stores read-only application (401) including the instructions for development of transaction interface (404) for user to execute the electronic transaction. Besides, it comprises unit (2303) for processing and storing of transaction data in latent area (2322). Transaction data (402) kept in latent area (2322) can be accessed solely by processing unit (2303). Besides, processing unit (2303) allows the device processor (20) to access the working area (2321) so that processor (20) executes said read-only application (401). Processing unit (2303) responds to processor (20) control efforts to get the access to transaction data (402) stored in latent area (2322). Besides, it incorporates display module (22) controlled by processor (20) for display transaction interface (404) when processor (20) executes read-only control application (401).
EFFECT: higher safety of transactions.
