4. The method of claim 1 , wherein said detecting by the smartphone that a proximity condition is satisfied between the smartphone and the entity is based, at least in part, on receiving a short-range signal from the entity over the first air interface.

5. The method of claim 4 , wherein said detecting by the smartphone that a proximity condition is satisfied between the smartphone and the entity is based, at least in part, on a measurement of signal strength of the short-range signal.

6. The method of claim 1 ,

wherein a value of the physiological parameter is provided by using a sensor of the smartphone.

7. The method of claim 1 , wherein said wirelessly providing by the smartphone, using the first air interface, information to the entity comprises:

being proximate to a specific location within a store, then detecting a short-range signal being transmitted from said specific location within the store, and then performing a transaction to pay for one or more items.

8. The method of claim 1 ,

wherein the entity comprises a check-out counter in a store, and

wherein said wirelessly providing by the smartphone, using the first air interface, information to the entity comprises:

performing a financial transaction to pay for one or more items.

9. The method of claim 1 , wherein establishing the wireless short-range communications link between the smartphone and the entity is performed in response to the physiological parameter.

10. A system comprising:

a smartphone that is configured to perform operations comprising:

detecting by the smartphone that a proximity condition is satisfied between the smartphone and an entity;

in response to at least the proximity condition having been satisfied between the smartphone and the entity, establishing a wireless short-range communications link between the smartphone and the entity to provide by the smartphone, using a first air interface, information to the entity and to receive by the smartphone information from the entity;

in response to at least the proximity condition having been satisfied between the smartphone and the entity and in response to a physiological parameter, wirelessly providing, using the first air interface, information to the entity and wirelessly receiving, using the first air interface, information from the entity independently of, and absent involving the entity in, receiving a communications service from a wireless network using a second air interface that differs from the first air interface; and

wirelessly receiving, using the second air interface, the communications service from the wireless network absent involving the entity, absent providing information to the entity, and absent receiving information from the entity,

wherein the wireless short-range communications link used by the first air interface is based upon unlicensed frequencies,

wherein the second air interface uses a wireless communications link that is based upon licensed frequencies, and

wherein the first air interface is not involved in providing the communications service to the smartphone.

11. The system according to claim 10 , further comprising the entity.

12. The system of claim 10 ,

wherein said wirelessly providing, using a first air interface, information to an entity and wirelessly receiving, using the first air interface, information from the entity independently of, and absent involving the entity in, receiving a communications service from a wireless network using a second air interface that differs from the first air interface is performed over a first time interval;

wherein said wirelessly receiving, using the second air interface, the communications service from the wireless network absent involving the entity, absent providing information to the entity, and absent receiving information from the entity is performed over a second time interval; and

wherein the first and second time intervals are non-overlapping with one another.
