Challenge: Create a working prototype of Mobile Wallet that can transfer offers and loyalty cards over NFC to a point of sale


  • Coordinated activity with wallet team, applet developer and point of sale (POS) technical lead to refine the interfaces descriptions
  • Defined set of prototype offers and loyalty card data
  • Obtained snapshot of modules that composed the user interface and the SIM based applet for sending offers and loyalty information over the NFC interface
  • Built code to intercept the UI events, assembled the offer and loyalty data, and pass the data to the NFC applet
  • Tested and debugged all components (until they worked) by reaching out across development¬† teams
  • Successfully demonstrated the first working wallet that sent offers from the handset to the POS by tapping the handset (with wallet) on the POS
