Abstract: A system for performing electronic transaction includes: a payment terminal including a human interface module, a first processor, and an internal bus for connecting these elements; a host terminal connectable to the human interface module through a connection; and a security module. The human interface module includes a keyboard, a display, a card reader for reading and authenticating a bank card or credit card. The host terminal includes a second processor, a memory, and a power supply. A transaction terminal task manager is included in the first security module, the first security module being hosted in the host terminal. The human interface module executes transaction phases under control of the security module, and executes security treatments, totally autonomously from the host terminal. The security treatments include presentation of a PIN code to the bank card or credit card.
