Ironically just picked up a Zebra EM45 RFID recently.

I turned on the RFID scanner and did a leisurely stroll through a local Walmart Supercenter.

I read nearly 6200 unique tags over 39,000 times in the span of a ~20 minute walk in the store. Every single tag has a unique serial number and a unique serialized EPC GTIN.

RFID/EPC enabled merchandise is going to be a huge trackpoint for passive RFID scanning moving forward. Walmart attempted this back in the early 2010s (and failed because it cost so much) and now that tags are pennies a tag, they can finally force suppliers to roll it out (starting with apparel, then hardlines over time).
