Stores like for us as consumers to give them a customer ID to track what it is that we are buying. Many have phone number or a card or an email address. They use this information to track our purchases and personalize their nudges for us to buy products. There is one way they might improve customer loyalty: Recall notices.
I pay attention to the news, so I see recalls every week. But, I doubt I am seeing them all. And, I doubt that I can reliably say whether I have the recalled item. But, the store where I bought it probably does.
A couple years ago, I was in a grocery aisle mulling over what to select when a manager came through to take off the shelf something nearby. He had a scanner which told him the information about the recalled item.
What would be really cool is if the system that is telling the stores what to pull from their shelves, looks through the customer purchases and informs the customers. They could pass along the recall notice and let the customer identify the lot number the same as the store. (I knew the manager was working a recall notice because he was talking to himself.)
Thinking maybe this already exists as an opt-in, I checked the stores where we have web site accounts. Nothing. (Given these places tend to go with an opt-out model, I was not surprised.)
