Align two subfigures vertically

Question

I'm writing a LaTeX document where I want two or three QR codes vertically aligned with caption on each. Unfortunately the first QR code is always one line lower than the other QR codes and I can't figure out why.

I have a workaround with negative \vspace, but I'm hoping to find the error or something neater.

MWE

\documentclass[12pt,a5paper]{book}
\usepackage[]{qrcode}
\usepackage{subcaption}
\begin{document}

\begin{figure}[ht]
    \centering
    \begin{subfigure}[t]{0.2\textwidth}    
        \centering        
        \qrcode[]{Text1}
       \caption*{Text1}
    \end{subfigure}
        \qquad
    \begin{subfigure}[ht]{0.2\textwidth}
        \centering    
        \qrcode[]{Text2}
        \caption*{Text2}
    \end{subfigure}      

\end{figure}
\end{document}

Answer 1

You can use \subcaptionboxes as they get vertically aligned automatically:

\documentclass[12pt,a5paper]{article}
\usepackage{qrcode}
\usepackage{subcaption}

\begin{document}
\begin{figure}[ht]
  \centering
  \subcaptionbox{Text1}{\qrcode{Text1}}
  \qquad
  \subcaptionbox{Text2}{\qrcode{Text2}}   
\end{figure}
\end{document}
