This type of thing is "product manufacture" only. Many do this to
protect themselves from being copied.

Hello,
I am looking for the manufacturer and any data about
these two ICs (SO-8 package) with smd marking : M61. for the receiver
and FL-A for the transmitter . These boards constitute an emitter
and a recepter for not loosing a suitcase . So it is a gadget that
may probably be manufactured in Asia area.
picture of the ICs on the boards is available here
