Chip cards have been out for almost a year. Does it make any sense how they're being handled?

My credit card company sent out replacement cards about a year ago with the new chips that are supposed to make things more secure. I think that the card regulations were supposed to go into effect last fall.

Here’s what I have experienced so far:

1) CVS – takes the chip card, asks for a signature. No PIN. Takes longer than sliding the card used to take.

2) Target red card – takes the chip card, PIN required. No signature.

3) Trader Joe’s – takes the chip, asks for signature.

NOWHERE ELSE – every other place I use a credit card – restaurants, gas stations, grocery, clothing, whatever…. I use the ‘slider’ that reads the magnetic stripe. No difference from previous years.

So what’s the deal? Why did the banks do all this if nothing has changed? If three companies in the US are actually using the chip readers, then what was the point?

What’s your experience?
