Item 4.

Purpose of Transaction

The Reporting Persons collectively are the beneficial owners of 2,482,039 shares of Common Stock. The Reporting Persons acquired Issuer’s securities reported on this Amendment No. 1 to Schedule 13D because they believed such securities represented an attractive investment.

On June 16, 2006 the Reporting Persons filed a Schedule 13D stating that the Reporting Persons had become concerned with the direction Carreker’s Board of Directors has taken with respect to Carreker’s business strategy, operations, and future. Mr. Riley had expressed his views that shareholders would be most rewarded by the sale of the Company and believed that any other means to get the “scale” in the operations would not be in the best interests of shareholders. Specifically, Mr. Riley believed that the company’s operating expenses were too high and these costs had served to mask the profitability that a strategic acquirer would achieve in an acquisition of the Company. Additionally, Mr. Riley has expressed his belief that any strategy to the contrary, most notably an acquisition by Carreker of another company in an attempt to achieve “scale” is not acceptable. Mr. Riley initially raised these concerns in discussions with Carreker’s management on June 8, 2006. Mr. Riley intends to suggest one or more persons for

(Page 5 of 10)

CUSIP No. 144433109

SCHEDULE 13D — AMENDMENT NO. 1

membership on Carreker’s Board of Directors. He will continue discussions with Carreker’s Board of Directors about his nominees to the Board and his concerns. If Mr. Riley’s concerns are not adequately addressed, he may nominate candidates for election to the Board at Carreker’s upcoming Annual Stockholders’ Meeting.

The Schedule 13D stated that Mr. Riley was contemplating a confidentiality agreement with Carreker as a basis for further discussion, which the Reporting Persons would file as an amendment to this Schedule 13D if executed. Pursuant to this previous statement, Mr. Riley has entered into a confidentiality agreement with the Company dated June 20, 2006, which is attached as Exhibit A.

Except as described above in this Item 4, the Reporting Persons do not have any plans or proposals that relate to, or would result in, any actions or events specified in clauses (a) through (j) of Item 4 to Schedule 13D. However, the Reporting Persons may determine to change their investment intent with respect to the Issuer in the future. The Reporting Persons intend to vote their respective shares of Common Stock individually as each Reporting Person deems appropriate from time to time. In determining whether to sell or retain their shares of Common Stock, the applicable Reporting Person will take into consideration such factors as it deems relevant, including without limitation Issuer’s business and prospects, anticipated future developments, existing and anticipated market conditions, general economic conditions, and other opportunities available to the Reporting Person. Each of the Reporting Persons reserves the right to acquire additional securities from Issuer in the open market, in privately negotiated transactions, or otherwise, to dispose of all or a portion of its holdings in Issuer’s securities, or to change their intention with respect to any or all of the matters referred to in this Item 4.

Item 5.

Interest in Securities of the Issuer

(a)

SACC Partners LP owns 2,282,039 shares of Common Stock. Because Riley Investment Management LLC has sole voting and investment power over SACC Partners LP’s security holdings, and Mr. Riley, in his role as the sole manager of Riley Investment Management LLC, controls its voting and investment decisions, each of SACC Partners LP, Riley Investment Management LLC, and Mr. Riley may be deemed to have beneficial ownership of the 2,282,039 shares owned of record by SACC Partners LP, which represent approximately 8.98% of Carreker’s outstanding Common Stock.

One of Riley Investment Management LLC’s client owns 200,000 shares of Carreker’s Common Stock. Although Riley Investment Management LLC, and Mr. Riley, in his role as sole manager of Riley Investment Management LLC, maintain shared voting and investment power over the 200,000 shares of Common Stock, Riley Investment Management LLC and Mr. Riley disclaim beneficial ownership of such shares, which represent approximately 0.79% of the outstanding Common Stock.

(b)

Mr. Riley has sole power to vote and dispose or direct the disposition of all shares held of record by SACC Partners LP.

(c)

There have been no additional transactions in Carreker’s Common Stock since the Reporting Persons filed a Schedule 13D dated June 8, 2006, which was filed with the Securities and Exchange Commission on June 16, 2006.

(d)

As the beneficial owner of 200,000 shares of Carreker’s Common Stock, Riley Investment Management LLC’s client referenced to above is entitled to any dividends or proceeds paid, not any of the Reporting Persons.
