    Evacuation Tracking: Accounting for Students, Employees with Barcode Scanning

    Implementing Mustering Systems

    Mustering systems that utilize an employee’s RFID badge can efficiently track the location of those badges if set up properly.  However, the cost to implement RFID systems can be high. Especially, consider the RFID ID cards, the RFID sensor hardware, and the deployment of those sensors.

    Also, many ask how to use the codeREADr app to help administrators during emergencies. Remarkably, our app will be a simple-to-deploy, and low-cost evacuation headcount app for the use case. Particularly, in this article, we’ll give you helpful information for your testing and evaluation.

    What does the codeREADr app offer?

    • First, you can track employees, students, or contractors during emergencies in real-time
    • Secondly, authorized staff members can participate in the tracking process
    • Thirdly, your staff can scan with their personal smartphones and tablets and/or provisioned scanning devices
    • Fourthly, you can use your existing IDs  if they are already barcoded. However, if they are not, simply add a barcode label. Here, you don’t need to create new credentials
    • Lastly, you do not need to install a new hardware or back-end software

    Basic Setup

    Scanning Devices

    Any Apple or Android smartphone or tablet (or iPod Touch) that has a built-in, autofocus camera. You can purchase and provision the devices authorized app-users. Also, you can have the users use their own smartphones and tablets.


    First, you can use the Free Plan to test. Annual licensing plans start at $499/year. That includes the use of up to 10 devices for scanning badges. Alternatively, you can contact for higher volume pricing. Also, contact us for consulting options for building your mustering services and training.


    1 – First, the IDs holders should already have a barcode to scan. However, if they don’t, you can issue barcode labels to affix to their IDs. In addition, you can have them use a program like ID123 for a digital ID. Importantly, it’s possible to use the app’s Lookup feature and not scan barcodes. However, that is usually if the ID-holders don’t have their ID for scanning.

    Note: Also, you can use RFID/NFC reading instead of a barcode scan. Here, the ID should include RFID/NFC chip and the scanning device have RFID/NFC.

    2 – Secondly, upload a list (CSV file) of IDs in advance to the codeREADr servers. Fortunately, this process takes less than a minute. Ideally, that list would be the IDs and names of the ‘currently present’. Alternatively, that list could be all IDs and then continuously reconcile during the emergency.

    Note: Alternatively, you can manage scan data by auto-exporting your scan records to third-party database programs. Moreover, you can use our APIs and Postback options to post scan records to your server or third party servers.


    1 – Primarily, regular drills will make the mustering process more efficient.

    2 – Secondly, assign specific mustering areas with each location sharing one or more characteristic (room, floor, building, etc).

    3 – Thirdly, assign administrators to be the ‘leader’ of a group of ID-holders mustering to a defined location.

    4 – Also, you should pre-install our app so you can prepare in advance.

    5 – Importantly, at least one person must be familiar with managing data and updating database on the web.

    6 – Furthermore, consider internet connectivity for syncing scans and databases to a server. You can set up codeREADr to work online if connectivity is stable. Alternatively, you can set it as ‘on-device’ (offline) with Auto Sync in the background if there’s at least some connectivity.

    Notably, with on-device scanning, validation is instant since there’s no Internet latency. Therefore, we highly recommend it for continuous scanning applications. Also, when there’s no connectivity, the app can still scan. Importantly, it will validate for uploading when the internet connectivity is back.

    Generally, it is fine for the devices to use your existing Wi-Fi system and the system is intact. However, if a cellular network is the only internet access, the connection may be slow with many people. Therefore, it is important to check and prepare alternatives. For example, you can set up a dedicated Wi-Fi hotspot at each designated mustering location. After that, you can have the app users to connect to the hotspot in advance.
