I'm going to be travelling around South America, and will be taking precautions to remain safe. I'm staying in hotels, not hostels, and will have guides with me a lot of the time. (Travelling with DP). However, I've heard there are still a lot of muggings, and some in broad daylight in full view of other people. Would it be a bad idea to take with a couple of expired credit cards / fake ones in a wallet, with a few dollar bills, and receipts that would look like a genuine wallet I could hand over in the event of it happening, and I can keep my passport and genuine cards in a hidden purse under my clothes? How do I even go about getting that sort of thing (eg if I use an expired genuine card, then they have my name). Am I being ridiculous? Amazon sell a decoy wallet for about £70 which seems a lot but indicates it is a thing?! Any suggestions or tips v welcome. Thank you!
