magnetic card readers

Continuing in the series of fun recycling projects for these Dell Vostro 200 computers, I purchased a MagTek Dynamag USB-based swipe card reader for a new project to track visitors in the office’s entrance.

Overview

The solution includes an Ubuntu server which only runs a single application to receive the card swipe details, to find the Track 1 data and to then submit this information to a Microsoft IIS—based website. The pages here then offer up an API for the incoming card swipe details and an administrative page for registering new visitors, reviewing the log details and the visitors as seen, to include the ability to export those details to Excel. The data is stored in a Microsoft SQL Server database.

To save cost, I decided to have each visitor just use a magnetic swipe card already in their wallet. In this way, I wouldn’t have to buy a magnetic card encoder, purchase card blanks nor worry about designing or issuing them (or trying to get them back later).

Typical Cost of an Access Control System for Visitors

From this webpage 2016 Average Card Access Cost

“Expect to pay an average of $1,500 to $2,500 per door for a high-quality system for up to 150 people. … It will cost an average of $1,000 to $1,500 for the hardware for the door. It will cost an average of $3 to $5 per keycard. Monthly service fees can range from $10 to $100 per month.”

My total cost for this project was just eight hours’ labor plus the $48.36 for the card reader! This included the database and website coding plus the I.T. work to setup the Ubuntu server and to create the Python script to talk to the USB-based reader, to test everything and to write up the documentation. This isn’t bad, considering the cost of an average system.
