/*
Note:
All data are stored in the card in binary format.
However, the data will be converted into hexadecimal character format when we read it via the card reader API.
In binary format, one character's length is 1 byte,
and 1 character can be represented using HEX format which needs 2 characters(thus the length becomes 2).
For example, decimal:255 ---> binary:1111 1111 (length: 1 byte)---> hexadecimal: 0xFF (length: 2 bytes---'F''F').
This is the reason why the length of data read from card are always 2 times of the length of it's inner storage format(binary).
