(30 ILCS 320/2)
(from Ch. 102, par. 62)
Any authorized officer, after filing with the Secretary of State
his manual signature certified by him under oath, may execute or cause to
be executed with a facsimile signature in lieu of his manual signature:
(a) Any public security, provided that at least one signature required
or permitted to be placed thereon shall be manually subscribed, and
(b) Any instrument of payment.
Any authorized officer may designate a deputy in writing manually to
subscribe the signature of any authorized officer to any public security or
to a certificate thereon to which the signature of the authorized officer
is required to be manually subscribed. The written designation of the
authorized officer shall be filed with the Secretary of State together with
a manual signature, certified under oath, of the deputy designated to sign
for the authorized officer.
Upon compliance with this Act by the authorized officer, his facsimile
signature has the same legal effect as his manual signature.
