Product reservoir validation system

1. A product dispensing system, comprising:

a refill unit containing a dispensable fluid product, the refill unit having an outlet;

a dispenser housing for retaining the refill unit, wherein the refill unit is removable from the dispenser housing;

a pump for pumping fluid out of the refill unit;

a pump actuator for causing the pump to pump the fluid;

a read-write data storage device secured to the refill unit, the read-write data storage device storing status data; and,

a dispenser control having a first logic processor and dispenser memory;

wherein the first logic processor receives at least one piece of status data indicative of the amount of fluid in the refill unit and at least one piece of data indicative of the identity of the refill unit from the data storage device;

wherein the dispenser controller determines if the identity of the refill unit is within a threshold data and dispenses fluid if the identity of the refill unit is in the threshold data; and

wherein the dispenser controller writes status data to the read-write storage device that includes the volume of fluid removed from the refill unit;

wherein the refill unit comprises an on-board power source that is removed from the dispenser with the refill unit and inserted into the dispenser with the refill unit.

2. The product dispensing system of claim 1 , wherein the status data is encrypted.

3. The product dispensing system of claim 1 , wherein the on-board power source is one or more batteries.

4. The product dispensing system of claim 1 , wherein the refill unit comprises a container and a collar secured to the container, and wherein the on-board power source is located on the collar.

5. The product dispensing system of claim 1 , wherein the pump is connected to the refill unit and is removed and replaced with the refill unit.

6. The product dispensing system of claim 1 further comprising two or more contacts for transferring power from the on-board power source to the dispenser.

7. The product dispensing system of claim 1 wherein the read-write data storage device comprises data indicative of the refill expiration date.

8. The product dispensing system of claim 1 wherein the read-write data storage device comprises data indicative of an authorization code.

9. A product dispensing system, comprising:

a refill unit containing a dispensable fluid product;

a dispenser housing for retaining the refill unit;

a pump for pumping fluid out of the refill unit;

a read-write data storage device secured to the refill unit, the read-write data storage device storing encrypted status data; and,

a dispenser control having a dispenser processor and dispenser memory;

wherein the dispenser processor wirelessly receives at least one piece of status data indicative of the amount of fluid in the refill unit and at least one piece of data indicative of the identity of the refill unit from the data storage device; and

wherein the dispenser processor wirelessly writes at least one piece of status data to the read-write data storage device that includes the volume of fluid remaining in the refill unit;

wherein the refill unit comprises an on-board power source that is removed from the dispenser with the refill unit and inserted into the dispenser with the refill unit.

10. The product dispensing system of claim 9 , wherein the dispenser processor wirelessly receives at least one piece of status data from the read-write data storage device that is indicative of the expiration date of the refill unit; and wherein the dispenser processor allows dispensing of the fluid product if the expiration date of the refill unit has not passed and prevents dispensing of the fluid product if the expiration date has passed.

11. The product dispensing system of claim 9 , wherein the on-board power source is one or more batteries.

12. The product dispensing system of claim 9 , wherein the refill unit comprises a container and a collar secured to the container, and wherein the on-board power source is located on the collar.

13. The product dispensing system of claim 9 , wherein the pump is connected to the refill unit and is removed and replaced with the refill unit.

14. The product dispensing system of claim 9 further comprising two or more contacts for transferring power from the on-board power source to the dispenser.

15. A product dispensing system comprising:

a dispenser housing;

a removable and replaceable container containing a dispensable fluid product;

a holder for retaining the removable replaceable container;

a pump for pumping fluid out of the container;

a read-write data storage device secured to the container, the read-write data storage device storing status data; and,

a dispenser control having a dispenser processor and dispenser memory;

wherein the dispenser processor is configured to wirelessly receive at least one piece of status data indicative of the amount of fluid in the container;

wherein the dispenser processor is configured to wirelessly receive at least one piece of data indicative of the identity of the container from the data storage device;

wherein the dispenser processor is configured to wirelessly receive at least one piece of data indicative of the authenticity of the container from the data storage device; and

wherein the dispenser processor wirelessly writes at least one piece of status data to the read-write data storage device that includes the volume of fluid remaining in the container;

wherein the refill unit comprises an on-board power source that is removed from the dispenser with the refill unit and inserted into the dispenser with the refill unit.

16. The product dispensing system of claim 15 , wherein the status data is encrypted.

17. The product dispensing system of claim 15 , wherein the on-board power source is one or more batteries.
