    Barcodes need line of sight with scanners and close range. RFID detectors can sense tags at larger distances and just based on general proximity.

    BLE is also an option, comparison to RFID would depend on setup particularities. RFID would be the more natural choice for throwaway, recyclable stickers that just need to store a short “dumb” ID.
