AuthID (AUID) filed a preliminary prospectus for the resale of up to 4.64 million shares by selling stockholders.

The offer consists of up to 4.07 million shares issuable upon exercise of stock purchase warrants and 572,852 fee shares, both issued in connection with a private placement that closed on April 29, the company said Wednesday in the regulatory filing.

The company won't receive any proceeds from the sale by stockholders, though it would get cash from nay exercise of the April warrants.
