TMS Software released a free component called TTMSFMXZBarReader which will read a QR Code on IOS using Delphi XE5 Firemonkey with two lines of code. It uses the open source ZBar library to do so. There is also a solution for Android which is more convoluted. The Android code to read QR codes seems to be a blend of code from Jim McKeeth, John Whitham, and Thomas K. Jim McKeeth from Embarcadero did a Webinar about gadgets and devices which has a QR reader demo project. Once you get the source code for the Webinar the QR code Android demo is called ‘Delphi Barcode Readers.zip’. John Whitham has a page up where he explains how to read QR codes using the Zxing library. And Thomas K posted some codes in the comments of the TMS Software blog post where he combined the TMS Software component with code from Jim McKeeth to handle IOS and Android with the same component (however it seems like it still need the Zxing library to work). Looks like you’ll have to do your own experimenting to get the Android code to work.
