ECD deputy commander Pol Colonel Kitti Sapaothong was responding to a YouTube video that shows how the device works and a subsequent rumour that it was already in Thailand.
He said there had been no reports of crimes using the device and that the ECD had already dispatched officers to China so they could become familiar with new skimmer tricks.
ECD 5 deputy chief Lt-Colonel Jakkrit Seributr said the agency had worked closely with banks to prevent skimmer crime and so far no bank had reported an offence occurring with the new device.
