Abstract
A portable, hand-held terminal processes products selected by a customer. A database of a host computer stores attribute data, such as price, of many products. The database is accessed by wireless transmission on a real-time basis to automatically retrieve the stored product attribute data. The retrieved data is printed by a printer and/or displayed on a display associated with the terminal.
Claims17
A method of processing transactions of products, comprising the steps of:
- a) storing and periodically updating product attribute data corresponding to each product in a common database of a host computer;
- b) providing a portable, hand-held terminal containing an electro-optical scanner for reading bar code symbols to each customer for the products, and having a respective customer hold the terminal and operate the scanner with one hand in a hand-held reading mode to read a respective symbol to identify a respective product;
- c) manually entering information relating to the respective product via a keyboard at a highest upper wall of the terminal in the reading mode and accessible to another hand of the respective customer from directly behind the terminal in the reading mode;
- d) transmitting the identified product to the host computer, by wireless transmission in one direction, on a real-time basis to automatically retrieve the stored, updated product attribute data corresponding to the product selected by the customer;
- e) transmitting the stored, updated product attribute data to the terminal, by wireless transmission in an opposite direction, on a real-time basis to automatically deliver the retrieved, updated data;
- f) printing the retrieved, updated delivered data at the terminal;
- and
- g) directly viewing displayed information relating to the identified product via a display at the highest upper wall of the terminal in the reading mode and viewable to the respective customer from directly behind the terminal in the reading mode.
