(2) C3 close to pin V
CC
of TDA8002C.
(3) C4 close to C1 contact of card reader.
(4) C5 close to VUP pin of TDA8002C.
(5) C6 as close as possible to pins S1 and S2.
CLK line may be shielded with respect to other lines.
Decoupling capacitors C7, C8 and C9 may be placed as close as possible to pin V
DDA
and V
