Transparency. It became one of the keywords in the feud that has recently been created in the debate between cash payments or through new digital tools.

While consumers are still use to pay with cash for different types of transactions, the use of digital payment instruments remains an indispensable weapon for combating tax evasion.

Right now, the duplicity in payment options has brought problems to the world's leading home sharing giant, Airbnb.

The so-called "Airbnb Law", which came into force on June 1, 2017, provides a 21% transaction, "for short rents of less than 30 days, stipulated by individuals directly or through entities that carry out real estate brokerage, including through the management of online portals ".

The measure, in addition to damaging the American giant, also challenges the hosts (those who make available a space to rent) that according to this new tax will have to turn into improvised hoteliers, paying the tax with the tax form.

Without going into the consideration of legal base of the story, the case opens a further split between the two types of payment that, as often announced, are not in a never-ending state of opposition, but on the contrary they are looking for a way to live peacefully together.

For Airbnb, in fact, the sentence damages "the only glimmer of transparency in a sector where 7 payments out of 10 still take place in cash". In fact, the tax could push many registered homeowners on the US portal to migrate to platforms where cash payment is easier.

In short, an economic system that could have been the promoter and protector of digital payments and that consequently was supposed to encourage the reduction of cash, to curb untraced transactions, could actually suffer a sharp slowdown.
