The high-pressure tactics used by smooth-talking conmen in Tenerife to fleece thousands of elderly British holidaymakers in credit card scams can be revealed today.

MailOnline witnessed gangs of suspected fraudsters deliberately targeting older Britons while ignoring younger tourists on a promenade on the south of the island.

Scores of British pensioners have fallen victim to the fraud which typically involves them being offered a laptop, , phone or a similar device for an attractive price.

The scam takes place when fraudsters working in souvenir shops use intimidating tactics to get their victims into the shop.

Once inside, they typically offer the vulnerable elderly tourist a device for a cut price.They ask to take a deposit of say 30 Euros to be taken on a debit or credit card – but when the customer inserts their card the unscrupulous store staff clone the card or steal their bank details.

Often they ask the holidaymaker to return to pay the balance – and ‘accidentally type in a far higher amount before asking the tourist to type in their pin without offering a receipt to confirm the purchase price.

Other versions of the fraud involve the scammers stealing PIN numbers or later charging a far higher fee than agreed using bogus bank debit forms.

Pensioners are often targeted on the last day of their holiday and typically only find out they have been conned weeks later when they check their bank or credit card statements.
