Considering the widespread use of contactless payment systems, it's no surprise that portable point-of-sale thefts are making a comeback. During the search, law enforcement allegedly found a modified portable POS terminal. The device shown in the photos circulated by the media appears to be a SumUp Solo, or a portable POS capable of operating independently without being connected to a smartphone. Fraudsters typically choose small amounts, trusting that the victim will not receive notifications—often the victim may not notice the amount being withdrawn, perhaps confusing it with other small transactions. Thefts using portable POS terminals can often be prevented by the fact that the smartphone must be unlocked, so even if someone places a POS terminal on the unattended phone, no transaction takes place.
