How to store a long data like RFID tag data in a postgres database? The RFID reader gives the BCD data converted into hexadecimal data of 24 bytes.
Example:cd00320000a4002a00001042 is the converted data given by the reader.
A:
There are many possibilities to do that.
It somewhat depends on what you want to do with the data.
But there seems also to be some confusion on your side: As the hex dump above has 24 digits, it is only 12 bytes worth of data, not 24. Which could be stored as 3 ints, or as string "cd00320000a4002a00001042", or ...
Question: How is the data stored in your java program, i.e. of what type is a variable where RFID data is stored?

agree.. a little vague on the question. my suggestion would be to store it as a string as well.
