             SEC FILE NO. 333-34882

Ladies and Gentlemen:

     As outside counsel to eRoomSystem Technologies, Inc., a Nevada corporation
(the "Company"), we are rendering this opinion in connection with the
registration by the Company of 2,070,000 shares (the "Shares") of the Company's
common stock, $0.001 par value, including 270,000 shares subject to an
over-allotment option, and the proposed issuance and sale of the Shares under
the Registration Statement.

     We have examined all instruments, documents and records which we deemed
relevant and necessary for the basis of our opinion hereinafter expressed. In
such examination, we have assumed the genuineness of all signatures and the
authenticity of all documents submitted to us as originals and the conformity to
the originals of all documents submitted to us as copies.

     Based on such examination and subject to the completion of all conditions
to closing provided under the relevant underwriting agreement, and subject to
such other limitations hereinabove provided, we are of the opinion that the
Company has the full corporate power and corporate authority under the laws of
the state of Nevada, and under its Articles of Incorporation and Bylaws to issue
the Shares and that such Shares are validly authorized shares of common stock of
the Company, and when issued and sold in the manner referred to in the
Registration Statement and in accordance with the resolutions adopted by the
Company's Board of Directors, will be legally issued, fully paid and
nonassessable.

     We hereby consent to the filing of the foregoing opinion as an exhibit to
the Registration Statement and to the use of our name in the Registration
Statement and in the related Prospectus under the heading "Legal Matters."

                                   Sincerely,



                                   KUMMER KAEMPFER BONNER & RENSHAW
