Looking for an individual to develop applications on the SIM using the Java Card api and Gemalto tool kit. End user should have proven expertise in sending/receiving sms and also USSD through the application on the sim card. This is a long term project for the right person once they have proven themselves with a sample project.
The sample project should entail an Java Card application on the sim card communicating to a server ( in this case a Gemalto server simulator ) and getting back information. Data is sent either as sms or as ussd messages (end user has the option of choosing which protocol) and can be simple data. the data in turn is internally encrypted with 3DES before being sent on the network and encrypted/decrypted on the server and the sim card application.
