Decoding RFID tag
Is anyone familiar with decoding RFID tags?
I have bytearray but idk where to start from here (Whihch part is tag value, which part specify it, etc.).
Any advice would be appreciated.

Sorry for "short" post, but i really don't know what else could i add that would be actually helpful.
what u encode into that bunch of bytes/how to interpret it is totally up to u,
there is no standardization
Tags may either be read-only, having a factory-assigned serial number that is used as a key into a database, or may be read/write, where object-specific data can be written into the tag by the system user. Field programmable tags may be write-once, read-multiple; "blank" tags may be written with an electronic product code by the user.(https://en.wikipedia.org/wiki/Radio-frequency_identification) basically u have to ask who ever set the value, how to interpret these bytes
ah so if two scanning apps show different results it doesnt mean either of them is wrong, it just means that they interprete it differently?
There would be multiple types of RFID card, I dont know upfront which types will be used..
well, if the readers would simply show the hex encoded bytes, they should display the very same value
