I think you must be confusing things or were told a lie. Bluetooth is a standard that is definitely not designed to be able to work like that. NFC is designed to work with thin tags that don't have a battery. Essentially they get power wirelessly from your phone in order to be able to send information. But, due to the inverse square law, you would need extreme amounts of power to be able to do that over a long range, so it just isn't something that could work with mobile phones.
