There are many different styles and types of retail security tags. In this post we will be exclusively talking about hard security tags and the pins that connect to them. Soft tags, security labels, or stickers do not use pins and thus are not relevant to this discussion.
The locking mechanism inside the hard security tag determines the type of pin required. Most but not all magnetic locking security tags can accept a standard flat head pin. Some exceptions are listed below. Supertags and Gator tags both use mechanical detachers and are not able to accept a standard flat head pin. Supertags use Supertag specific pins as do Gator tags. Almost all tags, both mechanical and magnetic, can accept universal ink pins.
