BasicCard® is the first smart card programmable in BASIC.

The BasicCard operating system takes care of all the communications for you. It will even encrypt and decrypt the commands and responds if you ask it to. All you have to do is specify a different two-byte ID for each command that you define. (If you are familiar with ISO/IEC 7816-4Interindustry commands for interchange, you will know these two bytes as CLA and INS, for Class and Instruction.)
