b) a system controller for receiving data representative of the identity of articles stored on the carrier and representative of a specific article to be dispensed, the controller being operatively coupled to the carrier to cause the carrier to move to a position in which the specific article to be dispensed is brought to the dispensing station;

c) a pick head at the dispensing station to engage an article, withdraw it from the carrier, and direct the article to a container; and

d) an article scanning station downstream of the dispensing station, the article scanning station comprising at least one scanner for scanning and identifying the selected article,

wherein the article scanning station further comprises a means for applying a label to the article, and wherein the means for labeling comprises;

a. a first scanner for scanning a first UPC on the article; and

b. a second scanner for scanning a second UPC on a label after the label has been applied to the article.

2. A method of dispensing a selected product from a plurality of products comprising:

a) providing an article dispensing system comprising an article scanning station, the article scanning station comprising at least two scanners for scanning a selected product;

b) selecting a product, each product comprising a pre-filled package containing at least one pre-selected item;

b) a system controller for receiving data representative of the identity of articles stored on the carrier and representative of a specific article to be dispensed, the controller being operatively coupled to the carrier to cause the carrier to move to a position in which the specific article to be dispensed is brought to the dispensing station;

c) a pick head at the dispensing station to engage an article, withdraw it from the carrier, and direct the article to a container; and

d) an article scanning station downstream of the dispensing station, the article scanning station comprising at least one scanner for scanning and identifying the selected article,

wherein the product dispensing station is further configured to;

scan a first UPC on the selected product using a first scanner, the first UPC being indicative of the identity of the pre-selected item;

identify the selected product based on the UPC;

label the selected product with a label corresponding to the identity of the selected product;

scan a second UPC on the label using a second scanner, the second UPC being associated with the identity of a patient intended to receive the pre-selected item;
