Abstract
A reference reader is provided for testing contactless electronic payment cards whose data transmissions are via weak load modulated RF carrier signals. The reference reader includes a reader antenna and a coupled common mode rejection circuit. The common mode rejection circuit is configured to demodulate carrier signals received at the reader antenna to retrieve payment card data signals having low modulation indices.
