If again the answer is yes too, than encrypted fax communications in a copy shop are the better option, at least for Bob to acknowledge the data reception from Alice, so that she knows that Bob received the data.
For encrypted Fax communications Alice and Bob can use my b2w encoder/decoder along with Google's format preserving encryption Adiantum, which I also offer. And if a Fax machine is not available Alice or Bob can send short voice encrypted messages with Adiantum too and use my bin2nato encoder/decoder, which beats internationally the PGP wordlist or mnemonicode, so that a six year old kid can use it internationally, while you can't do that with non-native English speakers using the PGP wordlist or mnemonicode.
