[Content updated September 27, 2015 – see the comments section further down]

The Alpha S3 Handkey was once a well guarded, enterprise-level device in which Alpha (a division of Checkpoint Systems, Inc.) successfully prevented mainstream use by way of restricting resale to authorised vendors.

Now, it is possible to purchase no-name replicas of the product, or even make one at home by obtaining instructions on how to make a do-it-yourself handkey.

We understand that, from time to time, their patent attorneys attempt to make contact with unauthorised resellers of this item with a cease a desist notice. Initially this may have been an effective solution, but in recent years the proliferation of generic S3 handkeys that have become available, has forced Checkpoint to rethink its strategy. Over time, this had led to the creation of self-alarming security tags and cables which emit an audible beep when they are detached. We will cover these in a later blog post.
