In Store TV & RFID

Engadget point us to news that Walmart is about to start narrowcasting from TV screens around their stores in Canada. They say:

[This] could mean that spots would air based on current buying trends or inventory levels. This dynamic approach to filling customers’ heads with ideas of what to purchase will supposedly “enable [Wal-Mart] to strategically reach out to guests in-store to inform, entertain and help save them money.”

But is this just a sign of things to come. The system, whether you like it or not, is rather unsophisticated, no? Retailers are continuously playing with tracking technologies like RFID. How narrow would those ‘casts be if they embedded chips in your cart or even in your club-card and tracked your movement and purchase behavior?
