Publication number: 20130015241Abstract: Techniques for negotiation techniques for mobile personal trusted device financial transactions are provided. A user of a mobile personal trusted device sets user preferences that define the user's preferred parameters for conducting financial transactions. A merchant sets merchant preferences that define the merchant's preferred parameters for conducting financial transactions. When a financial transaction is initiated, a user preference and a merchant preferences are accessed. A negotiated preference is generated that accommodates both the user preference and the merchant preference. If the user preference and the merchant preference are not mutually exclusive, the negotiated preference attempts to satisfy both preferences. If the user preference and the merchant preference are mutually exclusive, the negotiated preference satisfies at least one of the two preferences based on which of the two preferences has a higher priority. The financial transaction is conducted based on the negotiated preference.Type: ApplicationFiled: August 13, 2012Publication date: January 17, 2013Applicant: MasterCard International IncorporatedInventors: Jorge M.

Patent number: 8343525Abstract: An antiseptic cleaning agent, generally, comprising chlorhexidine acetate and a solvent, such as an alcohol and/or water. The chlorhexidine acetate acts as a highly effective biocide. Additionally, the chlorhexidine acetate allows the cleaning agent to dry without leaving a tacky residue. Where the cleaning agent comprises one or more alcohols, the alcohols may comprise any suitable alcohols, including lower alcohols having from 1 to 6 carbon atoms, such as ethanol and isopropanol. Where the ratio of ethanol to isopropanol may be from between about 1:1000 to about 1000:1. In addition to chlorhexidine acetate, the cleaning agent optionally comprises another non-alcohol biocide, such as triclosan. The cleaning agent can be used in any suitable manner. For instance, the cleaning agent may be impregnated in an absorbent material, such as a towelette, swabstick, or gauze. Additionally, the absorbent material may comprise a positively charged or a non-ionic substance, such as polypropylene or polyester.Type: GrantFiled: September 8, 2010Date of Patent: January 1, 2013Assignee: Becton, Dickinson and CompanyInventors: Bryan G.

Patent number: 7357319Abstract: An adaptor in accordance with the present invention allows a conventional magnetic stripe card POS reader to receive information from contact-based or wireless sources while maintaining the concurrent ability of the reader to interact with a magnetic stripe card. In accordance with one embodiment of the present invention, the adaptor includes an inductor capable of generating a magnetic field of sufficient power to couple with a head of a magnetic stripe card reader through the housing of the reader device. In this manner, the adaptor can be positioned external to the reader device, leaving the slot of the reader accessible for conventional interactions with magnetic stripe cards. Selective inductive communication with individual heads of the reader device may exploit their differing sensitivity to external magnetic fields generated by the adaptor.Type: GrantFiled: February 4, 2005Date of Patent: April 15, 2008Assignee: VIVOtech, Inc.Inventors: Li Liu, Mohammad A. Khan, Jorge M. Fernandes, Ahmer Ali Khan, Anna C. Stockel

Patent number: 7252232Abstract: An adaptor allows a magnetic stripe card reader to receive information from other media such as wireless proximity chip cards while maintaining the ability to receive a magnetic stripe card. In accordance with one embodiment, the adaptor includes a simulacrum structure of sufficiently narrow width to fit substantially permanently within the slot of the magnetic stripe reading device, while providing sufficient room for a magnetic stripe card to also be concurrently accommodated within the slot and read by the reader head. The simulacrum structure may be in electronic communication with one or more transceivers of wireless communications such as RF and IR.Type: GrantFiled: February 15, 2006Date of Patent: August 7, 2007Assignee: VIVOtech, Inc.Inventors: Jorge M.

Patent number: 7127236Abstract: A MicroAdapter device enables payment transactions to be effected through a purchaser's personal trusted device (PTD) without relying upon tokens or prepayment cards. In one embodiment, the MicroAdapter includes a transceiver configured to receive a purchase signal from the PTD including order and payment information. In response, the MicroAdapter communicates via wireless telephony with a transaction authorizer to receive authorization for effectuating the purchase transaction. The MicroAdapter may be particularly suited to effectuate micropayment transactions authorized by a Billing On Behalf of Others (BOBO) program administered through a wireless carrier/ISP or third party.Type: GrantFiled: December 18, 2002Date of Patent: October 24, 2006Assignee: VIVOtech, Inc.Inventors: Mohammad A.

Publication number: 20040159700Abstract: Embodiments in accordance with the present invention allow financial or other confidential information to be securely imported in electronic form into a PTD. The information to be imported is first encrypted. The encrypted information is then transmitted from a source to the PTD. The encrypted information is then stored by the PTD. A decryption key is sent to the PTD user in a manner establishing a strong non-repudiation scheme. For example, the decryption key could be sent from a second device, or through a second communication channel separate and distinct from the first communication channel. Utilizing the decryption key delivered through the second communication channel, the user is able to decrypt and access the information in the PTD for transactional purposes.Type: ApplicationFiled: May 2, 2003Publication date: August 19, 2004Applicant: VIVOtech, Inc.Inventors: Mohammad A.
