BLE vs. NFC: The future of mobile consumer engagement
great for passively enabling a retailer's mobile app to deliver promotions, coupons or offers direct to the consumer's smartphone when the consumer is in the general vicinity. NFC can't do that. But if you want to research a specific Nikon SLR, for example, you can scan an NFC-enabled shelf tag next to it and study to your heart's content. BLE can't deliver that much location granularity.
