The Ewent USB-A 2.0 Citizen Card Reader, reference EW1052, is a smart card reader compatible with the Portuguese citizen card and other ID-1 format cards. It connects to any USB-A port and does not require external power or the installation of additional drivers on most operating systems, functioning immediately after connection. It is compatible with ISO 7816 and EMV2000 Level 1 standards, ensuring correct recognition of the citizen card for authentication, digital signature, and access to online government services. It is a preferred option for those who need to use their citizen card on a desktop computer without an integrated reader.
