Item 1.	Security and Issuer
	This Amendment No. 1 to Schedule 13D (“Amendment No. 1”) relates to the Common Stock, $0.001 par value per share (the “Common Stock”), of Hypercom Corporation, a Delaware corporation (the “Company”), which has its principal executive offices at 8888 East Raintree Drive, Suite 300, Scottsdale, Arizona 85260.  This Amendment No. 1 amends and supplements, as set forth below, the information contained in items 1, 3, 5 and 6 of the Schedule 13D filed by the Reporting Persons with respect to the Company on August 31, 2010 (as so amended, the “Schedule 13D”).  All capitalized terms used herein but not defined herein have the meanings set forth in the Schedule 13D.  Except as amended by this Amendment No. 1, all information contained in the Schedule 13D is, after reasonable inquiry and to the best of the Reporting Persons’ knowledge and belief, true, complete and correct as of the date of this Amendment No. 1.
Item 3.	Source and Amount of Funds or Other Consideration
	Item 3 of the Schedule 13D is hereby amended to read in its entirety as follows: The total purchase price for the 2,013,744 shares of Common Stock beneficially owned by Discovery Group and Messrs. Donoghue and Murphy as of October 13, 2010 was approximately $8,468,986.  The source of such funds was the assets of two private investment partnerships (collectively, the “Partnerships”) over which Discovery Group exercises discretionary investment management authority, and proceeds of margin loans under margin loan facilities maintained in the ordinary course of business by the Partnerships with a broker on customary terms and conditions.  The Partnerships are the legal owner of all of the Common Stock beneficially owned by Discovery Group and Messrs. Donoghue and Murphy.
Item 5.	Interest in Securities of the Issuer
	Item 5 of the Schedule 13D is hereby amended to read in its entirety as follows:   The information concerning percentages of ownership set forth below is based on 55,219,470 shares of Common Stock reported outstanding as of August 6, 2010 in the Company’s most recent Quarterly Report on Form 10-Q, for the period ended June 30, 2010. Discovery Group beneficially owns 2,013,744 shares of Common Stock as of October 13, 2010, which represents 3.6% of the outstanding Common Stock. Mr. Donoghue beneficially owns 2,013,744 shares of Common Stock as of October 13, 2010, which represents 3.6% of the outstanding Common Stock. Mr. Murphy beneficially owns 2,013,744 shares of Common Stock as of October 13, 2010, which represents 3.6% of the outstanding Common Stock. Discovery Group is the sole general partner of one of the Partnerships and has sole discretionary investment authority with respect to the other Partnership’s investment in the Common Stock.  Messrs. Donoghue and Murphy are the sole managing members of Discovery Group.  As a consequence, Discovery Group and Messrs. Donoghue and Murphy may be deemed to share beneficial ownership of all of the shares of Common Stock owned by both of the Partnerships.
	The transactions in Common Stock effected by the Reporting Persons since the date of the most recent filing on Schedule 13D are set out in Exhibit 1 hereto. Each of the Reporting Persons ceased to be the beneficial owner of more than five percent of the Common Stock on October 8, 2010. No person other than the Partnerships is known to any Reporting Person to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any of the shares of Common Stock reported herein.

Item 6.		Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
		Item 6 of the Schedule 13D is hereby amended to read in its entirety as follows: There are no contracts, arrangements, understandings or relationships (legal or otherwise) between or among any of the Reporting Persons and any other person with respect to any securities of the Company other than the governing documents of Discovery Group and the Partnerships, the margin loan facilities referred to under Item 3 above, the Joint Filing Agreement of the Reporting Persons with respect to the Schedule 13D that was included as an exhibit thereto, the Joint Filing Agreement of the Reporting Persons with respect to this Amendment No. 1 included as Exhibit 2 to this Amendment No. 1, and the Powers of Attorney granted by Messrs Donoghue and Murphy with respect to reports under Section 13 of the Securities Exchange Act of 1934, as amended, which Powers of Attorney are included as Exhibit 3 and Exhibit 4, respectively, to this Amendment No. 1.
