It supports both contactless and contact cards compiled to ISO 14443A and ISO7816 standards. Power is conveniently supplied directly via the USB port, and it offers wide compatibility across major operating systems including Windows, Linux, Unix, and Android.
The S9-BU-13-00 supports a broad array of card types, including S50/S70, DESFire, Pro, Ultralight, NFC cards/tags (NTAG213-216), and contact CPU cards.
