Appl. No.:

11/746524

Inventors:

Amy Swift - Albuquerque NM, US
Waisum Mok - Houston TX, US

Assignee:

First Data Corporation - Greenwood Village CO

International Classification:

G06Q 40/00

US Classification:

705 45, 235375, 705 35

Abstract:

The present invention is directed to methods and apparatus for processing check data, such as data stored using magnetic indicia. In one embodiment, a check transaction processing system receives an indication that a first check transaction from a first payor failed to clear because at least a portion of first MICR or other account data associated with the first check transaction is incorrect. The check transaction processing system reads a personal identifier associated with the first payor, wherein the personal identifier was provided in association with the first check transaction. MICR data or other account data associated with a previously processed check transaction associated with the personal identifier is located. At least a portion of the located MICR or other account data is compared with at least the portion of first MICR or other account data associated with the first check transaction, and based at least in part on the comparison, the check transaction processing system determines if the portion of the located data is at least a potentially correct version of the portion of first MICR or other account data.

International Classification:

G06K 5/00

US Classification:

235380, 235379, 235375, 705 45

Abstract:

Systems and methods are disclosed, where check transaction risks can be determined based on a pattern of changes in identifier information such as MICR field information and driver license number. A MICR field on a given check includes a routing transit number and an account number. Some fraudulent check transactions involve a pattern of alterations of the MICR field, such as changing, adding, or removing of one or more digits or characters of the account number or the routing transit number. Various embodiments of systems and methods can be configured to detect such pattern of changes in the MICR field, thereby facilitating detection of fraudulent check transactions. Various techniques of the present disclosure can be used to detect fraudulent electronic check transactions such as web-based transactions, as well as paper check transactions.
