Sure\nyou could use a stolen credit card or a fake $5 bill, but it's not worth\nthe risk of being caught for a $3 coffee. And on the other side, the store\ncan deal with 1% of transactions getting reversed or having a fake bill so\nthey don't change their procedures.\n\nPerfection is not necessary in all situations.\n\nOn Sat, Jun 20, 2015 at 12:02 AM, Eric Lombrozo \u003celombrozo at gmail.com\u003e wrote:\n\n\u003e\n\u003e \u003e On Jun 19, 2015, at 8:48 PM, Luke Dashjr \u003cluke at dashjr.org\u003e wrote:\n\u003e \u003e\n\u003e \u003e On Saturday, June 20, 2015 1:23:03 AM Aaron Voisine wrote:\n\u003e \u003e\u003e They don't need to be made cryptographically safe, they just have to be\n\u003e \u003e\u003e safer than, for instance, credit card payments that can be charged\n\u003e back.
