Lol... Yeah right... My wife's grandmother that lives out in El campo like 30 minutes walk to closest road that doesn't have any electricity or even close to any internet connection, even with a phone you don't have signal to connect. She has a colmado for the "locals", I believe we'll be seeing pigs fly before she can install any of those systems.... And also, what stops a barber or any other "micro" empresa from not providing a receipt?? You go in get your haircut and eithert pay 300 pesos "tax-free" or you pay 400 pesos with the tax included, what will you choose???
And I remember like 8 years ago when they tried to implement something like this, that they were obligating all business owners, registered or unregistered to have this system. It was NOT for free, you had to pay for it, if I don't remember incorrectly it was something like 50k-100k pesos for the system. So there was a great outcry about this among business owners, so they only implemented it to the bigger multi-million companies. So yeah, right.....
