How It Works

IndoTag Smart label

SDP-2 tag also known as Tag, transponder or responded. SDP-2 made of special , tag chip and antenna which immediately responds when a mobile/reader scans it but it not water proofed and scratch resistant. Smart label is capable to identify and verify the manufacturer of a product , which cannot be copied and thus its capable to avoiding duplicacy of the product of a manufacturer.

This tag is suitable for any surface except metal , like automobile parts, stainless steel , etc
