A method, system, computer program product, and device for providing
product information, such as, for example, product price comparison
information, product reviews, retailer information, retailer reviews, and
information about similar products, to a user utilizing a mobile data
processing system is provided. In one embodiment, a user, using a product
code reader, such as, for example, an RFID reader, reads a product code
from a tag, such as, for example, an RFID tag, located proximate to a
product. The product code information determined from the product code is
transmitted to a server. The server receives the product code information
and retrieves the product information from a database. The server then
formats the product information into, for example, a web page, and
transmits the web page back to the mobile data processing system which
receives the web page and presents the web page to the user.
