QR codes can be included when promoting podcast RSS feeds to allow users to easily subscribe to the feeds from their mobile phones. A QR code is a matrix barcode that can be scanned by a phone camera to link to a website, make a phone call, send a text, or transfer other information quickly. Creating and scanning QR codes is a simple process that only requires a QR code generator, barcode scanner app on a phone, and a camera. While many students may not currently be aware of QR codes, including them can make subscribing to podcast feeds or accessing other information from a mobile device convenient for those who do have QR scanning capabilities on their phones.
