Stickers could be replace RFID so that stolen retail goods could be tracked to a person’s home or fencing location. Police could then be alerted and goods recovered. This could also lead to discovering an entire cache of stolen goods.
To add on to this: since there may be concerns about stores tracking paying customers, I recommend that upon payment the stickers (which act as miniature Sentinels) either be shut off, have their ID reset, or have their ownership transferred to the customer, much like how current RFID stickers are deactivated when the product is paid for. If the store no longer has control over the sticker’s current address, it has no way of tracking the sold product.
