For interactions with the core banking system, 40 this simply means that we only accept payments from or to domestic bank 41 accounts. For P2P payments between wallets, we require that the wallets are 42 controlled by a domestic entity. We define domestic entities as those that 43 are able to receive messages at a domestic address. Two types of addresses are 44 supported: 45 46 \begin{itemize} 47 \item Control over a domestic {\bf mobile phone number} is established 48 by sending an SMS message with a confirmation code to the MSIN. 49 \item Control over a domestic {\bf postal address} is established by 50 sending a letter with a confirmation code to the address. 51 \end{itemize} 52 53 Depending on the type of address, a validation has a limited validity period, 54 as shown in Table~\ref{table:proc:domestic}. When the validity period is 55 over, a wallet has to re-do the address validation before they can receive any 56 further funds through the service. 57 58 \begin{table}[h!] 59 \caption{Restrictions on address validations} 60 \label{table:proc:domestic} 61 \begin{tabular}{l|l|r} 62 {\bf Type} & {\bf Validity period} & {\bf Restricted to} \\ \hline \hline 63 Mobile phone number & 12 months & {\em +41} \\ 64 Postal address & 36 months & {\em Switzerland} \\ 65 \end{tabular} 66 \end{table}
