Those with at least a passing familiarity with computing may be confused by this explanation of RAIN RFID Tag memory "blocks". So far as I can tell, "block" is not a term used in RAIN. What RAIN does describe are Memory Banks, and within those Banks, data is stored as Words. There are four Memory Banks: TID (tag id), EPC (or UII; product Id); User, and Reserved (used for things like passwords and locking). Within those banks, there are some number of data Words (varies according to chip), where a Word is defined as 16 bits, obviously equivalent to two bytes, or four 4-bit fields that can be displayed using hex notation as usual. When this video belabors the fact that you have to write an entire "block", this appears to be saying just that the memory is addressable word by word, which is to be expected. What would be quite useful to know is what baseline common features RFID chips are required to have (for example minimum tag id length), versus degree to which those features may be extended in different chip models and are thus the basis for distinguishing one chip from another (and tags that use each chip).

"schematic" -- If you're referring to a particular format, structure or organization of data, the term used in the database and IT realm is "schema". The word "schematic" usually refers to a diagram of some sort, like an electrical or electronic circuit diagram.

Nice video, would be cool if you could get a lot deeper into the encoding of EPC as this is still very superficial and not many people are covering this.

I want to learn more

Which one you prefer? Gs1 or rain?
