Travellers visiting Rio de Janeiro face a growing threat from beach vendors who manipulate card readers to overcharge unsuspecting tourists. Lisa Selby learned this lesson when purchasing two slices of barbecued cheese from a Rio beach vendor. She expected to pay 40 reais (£5.90) but discovered the vendor had added two extra zeros to the card terminal, charging her 4,000 reais (£590) instead.

Selby's experience is far from isolated. Other visitors reported staggering overcharges: one tourist paid £1,500 for a kebab, while another was charged £3,000 for corn on the cob. The scam operates through deliberate manipulation of point-of-sale terminals at informal beach food stalls throughout Rio de Janeiro's coastal areas.

The con works through a simple but effective method. Vendors position the card reader away from customers' view, then alter the transaction amount before processing payment. By the time travellers notice the fraudulent charge on their statements, the vendor has disappeared into the crowds.

The British Foreign Office and travel advisories now warn visitors about this specific scam. Experts recommend several precautions: avoid using debit cards for beach purchases; insist on seeing the card reader display before entering your PIN; use credit cards instead, which offer better fraud protection; and carry cash for small transactions at informal vendors.

Rio de Janeiro remains a major destination for British and international tourists seeking its beaches, Carnival celebrations, and iconic landmarks. However, these scams disproportionately target visitors unfamiliar with local street vendor practices. Tourists should exercise heightened vigilance when purchasing food from beach stalls, particularly in popular areas like Copacabana and Ipanema.

Travel insurers note that fraud losses from card manipulation rarely qualify for reimbursement, making prevention essential. Travellers
