From a promotional leaflet from German firm ADT (translated from the German original) for RFID solutions in retailing:

"Imagine your wares are intelligent. Something gets stolen - and gives off a signal that cannot be ignored. Canny, ain't it? Through the intelligent source protection from ADT every item, be it ever so small, can be thus outfitted, already at point of production. This is cost-efficient for you - and unvisible for the customer. And also cannot be disarmed by a special bag or a thick overcoat."

Texas Instrument shows how it goes:
This is how reading the RFID chip in the "loyalty" card in the handbag of a shopper works -- without any help from the customer. We quote: "A consumer with a TI-RFid tag in their purse, pocket, or wallet can be detected by reader systems at doorways. Readout antennas can also be in counters, walls, and in floors."

An article about customer specific marketing:
Customer Specific Marketing e.g. includes price discrimination: Make aggressive (low cost) offers to profitable customers. Raise prices for not so profitable customers. And: Special offers are exclusively for card holders that give up their personal data.
