None of the Phidgets RFID readers are capable of reading when more than one tag is within range. In general, it is problematic with passive tags because the activation power is spread across multiple tags, and even if they do both respond with their code, they will interfere with one another.

There are some HF and UHF readers that have this capability, but we only sell LF readers.
