Bell Electronics Lab Corporation situated in Calamba, Laguna is engaged in test and assembly of optoelectronics and sensor devices. The company is concentrating on its resources in metal can packaging. The second phase of the company's program is towards the development of other types of optoelectronics and sensors device packaging to support their customer requirements. In this paper, the proponents will present an Automated Inventory System using Portable Data Acquisition (PDA) module to help thecompany’s growing business. The PDA module is composed of barcode scanner to scan issued and received items, and a Z8F6423 Zilog microcontroler to sore the information. A Product Inventory System (PIS) application program is also discussed to show how the PDA module can be interfaced with the PIS. Test results presented in this paper will show apparent improvement of company’s inventory system.
