Using Javacards instead of MicroSD
There were a few key points that led to the usage of Javacards in comparison to SD Cards:
- 1.Users cannot check the genuinity of the SD card because custom logic can not be implemented.
- 2.MicroSD cards do not have flexible brute force prevention schemes.
- 3.Users can not directly communicate with phones through a MicroSD card. Javacards are NFC based and hence can directly communicate.
- 4.Since SD cards can not encrypt/decrypt data on its own, this inability hinders future product development and features, especially when it comes to working on crypto inheritance.
- 5.Javacards are battle tested for decades in the banking industry for developing credit and debit cards whereas Micro SD cards are more generally used for larger storage of non-sensitive information.
