Mobile wallet transaction system

Abstract

An electronic transaction card communicates with an add-on slot of an intelligent electronic device. The add-on slot may be a memory card slot. The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.

         2 . The transaction system of  claim 1  wherein the mobile device comprises a mobile phone. 
     
     
         3 . The transaction system of  claim 1  wherein the second interface comprises a memory card interface. 
     
     
         4 . The transaction system of  claim 1  wherein the first interface comprises a contactless interface. 
     
     
         5 . The transaction system of  claim 1  wherein the electronic transaction card is compatible with a smartcard reader. 
     
     
         6 . The transaction system of  claim 1  wherein the electronic transaction card further comprises a point-of sale interface coupled to the smartcard circuitry. 
     
     
         7 . The transaction system of  claim 1  wherein the electronic transaction system is configured to perform transactions. 
     
     
         8 . The transaction system of  claim 7  wherein the transactions are financial transactions. 
     
     
         9 . The transaction system of  claim 7  wherein the electronic transaction card is configured to operate as a credit card. 
     
     
         10 . A transaction system comprising:
 a mobile device; and   an electronic transaction card coupled to the mobile device, the electronic transaction card including smartcard circuitry for performing transactions.   
     
     
         11 . The transaction system of  claim 10  wherein the mobile device comprises a mobile phone. 
     
     
         12 . The transaction system of  claim 10  wherein the smartcard circuitry is configured to perform point-of-sale transactions. 
     
     
         13 . The transaction system of  claim 10  wherein the transactions are financial transactions. 
     
     
         14 . The transaction system of  claim 10  wherein the electronic transaction card is configured to operate as a credit card. 
     
     
         15 . A system comprising:
 an electronic transaction card having smartcard circuitry and a contactless interface to communicate with a host device; and   a host device compatible with the contactless interface of the electronic transaction card.   
     
     
         16 . The system of  claim 15  wherein the host device comprises a mobile phone. 
     
     
         17 . The system of  claim 15  wherein the electronic transaction card further includes a point-of-sale interface coupled to the smartcard circuitry. 
     
     
         18 . The system of  claim 15  wherein the host device includes a circuit to communicate over a network. 
     
     
         19 . The system of  claim 18  wherein the electronic transaction card is configured to perform transactions over the network.
