RFID Readers with Embedded Linux

This is very similar to the previous case, but here a small embedded SoC or CPU is built into the reader. This option allows the reader vendor to benefit from the network capabilities of the Linux OS and thus enables the user to directly attach a reader to an Ethernet network.

Particularly in supply chain/item management setups, we'll probably see such Ethernet-attached readers supplied by Power-over-Ethernet (PoE), similar to WiFi access points. Usually, this type of reader provides a very high-level interface to the backend/ application software. It is thus particularly unsuitable for security analysis of the lower protocol levels.
