Access Control | Handheld Detects Vehicles

One large oilfield in Chile used Chainway handheld computer to identify vehicles at the entrance for access control.

In one large oilfield in Chile, hundreds of vehicles of different types enter this area every month. Managing such a number of vehicles is a major challenge to the field owners. Combining RFID technology to automate vehicle identification with barcode technology is a proven effective solution for vehicle access control (VAC). 

The oilfield owners worked with Chainway Information Technology Ltd. (Chainway), a China-based handheld computer manufacturer, to build a vehicle access control system. Chainway offered handheld computers with RFID and barcode capabilities to read UHF RFID tags or 2D barcode labels on authorized vehicles.

Each tag has a unique ID number and is linked via software to a database with information about the vehicle – number plate, vehicle type, etc. When a vehicle enters the field, security personnel use Chainway handheld to scan the vehicle’s RFID or barcode tag at the gate. It identifies the ID number and other details immediately and send this information to the database to verify. If the tag is authorized, Chainway handheld computer shows a positive signal and the security guard opens the gate. Only authorized vehicles can access to the avenue. 

In the past, workers recorded vehicle information manually, which was highly inefficient and may cause undesired discrepancies. In the VAC system, automatic vehicle identification is realized and a fleet productivity report is generated automatically on a daily basis. It records accurate details of the vehicles entered and departure. 

Chainway designs, engineers and manufactures durable, high-performance handheld computers for specialized vehicle access control application. Together with IoT technologies including RFID and barcoding, this handheld terminal provides real time visibility of vehicle movement and quick, easy and detailed vehicle identification.
