Unfortunately I doubt you'll ever see this happen.

Sure, it's supposedly possible to buy an RFID chip for 1p - but you can buy a can of beans for 23p so that 1p is probably their entire profit margin.

I've also worked with a variety of RFID readers; none of them can provide reliable reading, even in favourable conditions.

I think there's another technical issue with using RFID. If you have a basket of a few dozen different RFID chips, there's going to be a lot of collisions in the data they transmit, further reducing reliability.

Exactly how many beans does this 23p 'can' contain? Is it more than a dozen?

If my Business Studies teacher ~20 years ago was, and still is, correct then they are a loss leader.
