The Spanish have a preference, deeply rooted in our culture, for cash to any proceedings in any other financial asset. That is why our country is rampant circulation of higher denomination notes such as those of 500. In addition to preferences for time to pay our purchases, the high demand that our country exhibits of 500 euro notes, stems from the abundance of so-called black money payments. Tax evasion is a reality in every country in the world, simply varies the amount and volume of transactions not reported to the respective treasuries. The operative cash versus other payment methods such as credit cards or bank transfers is an indispensable means for the realization of marginal

operations. That is why the tax office keeps in place a traffic control program of 500 euro notes.
