SMART CARDS HAVING LED AND METHODS FOR FABRICATION THEREOF

The present disclosure relates to a smart card device comprising: a laminated core comprising: a front substrate (10); a first flexible sheet (20) having a card circuitry formed thereon; a first substrate (30); a second flexible sheet (40) having an inductive circuitry formed thereon, and a second substrate (50) in a top-to-bottom order, wherein the front substrate (10) provides at least one first opening (11) which defines a perforated design and a second opening (12) through which a contact pad (22) is exposed, wherein the card circuitry includes: a flip chip (21), a first antenna coil (24) conductively coupled to the flip chip (21), the contact pad (22), at least one conductor path (23) conductively coupling the contact pad (22) to the flip chip (21), wherein the inductive circuitry includes at least one LED module (46) arranged proximate to the at least one first opening (11) and a second antenna coil (44) conductively coupled to the at least one LED module (46), and wherein the first substrate (30) includes at least one light guide (31) which is arranged under the at least one first opening (11) and configured to direct an illumination produced by the at least one LED module (46) through the at least one first opening (11) to illuminate the perforated design.
