An non-contact reading device for reducing a loading effect connects with a host to sense a non-contact card. The non-contact reading device includes an antenna carrier board and an electromagnetic-wave absorption barrier. The antenna carrier board includes an antenna to receive a first analog signal from the non-contact card and send a second analog signal to the non-contact card. The electromagnetic-wave absorption barrier includes an electromagnetic-wave absorption material and an insulation board. The electromagnetic-wave absorption material is adapted to attach onto the antenna carrier board and absorbs the electromagnetic wave. The insulation board is attached to the electromagnetic-wave absorption material to cover on the antenna carrier board and maintain a magnetic-field interference at a fixed value.
