Developers loved 1.6.1 because it was stable, well-documented, and royalty-free for internal applications.
– SDK 1.6.1 works best with U.are.U 4000B, 4500, and 5160. Newer readers (like 5300) require SDK 2.x.
– SDK 1.6.1 had no software license key for dev mode. Only runtime distribution required a key (now unobtainable).
