Greek authorities said on Monday they had arrested 24 people in a crackdown on about 1,000 small businesses suspected of dodging capital controls and value-added tax by using cashless card-processing terminals linked to banks in Bulgaria. Authorities said hundreds of small businesses - many in the tourism industry - were conducting cashless transactions using point-of-sales (PoS) devices linked to Bulgaria via Malta that went unrecorded in Greece, which has had capital controls in place for a year. "We arrested 24 people who were using PoS machines connected with banks outside Greece, in Bulgaria and Malta, to evade tax," Emmanuel Ploumis, head of the Greek police's economic crime squad told reporters.
