I doubt they use global unique identifiers.
RFID takes longer to read longer numbers, especially if there are many targets in the same field. So 32bit global ID for all chips would take a long time to read, possibly minutes if it's a table with 1000 chips on it.
A 4bit code that just ID'ed value and allowed you to spot if somebody had 'mistakenly' mixed up some low value chips in a stack would be much quicker. |
