An absorbent article adapted for use with a radio frequency reader comprising: an absorbent pad including a lining layer with a liquid-impermeable layer attached to it and an absorbent layer disposed betweenthe two. The lining layer and liquid-impermeable layer cooperate to define a first receiving space that has a first opening located at a first side portion of the pad, and a plurality of sensing wires provided on said absorbent layer and extending into said first receiving space; and a radio-frequency identification (RFID) tag removably received in first receiving space through said first opening and contacting electrically said sensing wires when received in said first receiving space, wherein said absorbent pad further includes an adhesive that adheres said lining layer to said liquid-impermeable layer, and that has a portion in said first receiving space to removably retain said RFID tag therein, and a release paper that is disposed between a portion of the adhesive and either the lining layer or the liquid-impermeable layer. This prevents the lining layer and liquid-impermeable layer from adhering to each other at said first receiving space.
