Anti-Skimmers - Bug Detectors
Ways to prevent skimming: personal methods are best done by being aware of the surrounding area, has there been unusual activities, are there new instructions on operation, has anything changed? Wireless cameras are intruding on our privacy and even cell phones are being used to capture private moments. Personal 'Bug Detectors' are not as expensive as frequency counters and are easy to use, IF WE REMEMBER TO USE THEM AND KNOW HOW TO OPERATE THEM.
There is another type of mini cam, which has a PIR option, the transmitter only transmits when there is motion detected, this would defeat the bug detector that would be looking for a long duration transmitter, but if fuzzy logic in the transmission time was employed, a transmission twice inside of thirty minutes (or hour) would also trip an alarm. The fuzzy alarm logic could be remotely programmable according to the latest intrusions detected. A remotely updateable alarm system could use the communication link of customer authorization data to turn off or on a feature if desired for a new attack in a particular area or country. The criminals seem to coordinate attacks as they find a new vulnerability.
With the problems of Skimming at ATMs, one solution is to notify the CUSTOMER to be on the alert for anything unusual. Just look around at the many varieties of ATM styles and note that the image on the instruction often does NOT MATCH the actual updated card reader from the manufacturer. Even when the instruction is consistent, the operation of one card reader to the one next door can leave a customer confused. The varieties include: slide down flat, slide up vertical, push in and pull out quickly, set card into slot and let motor pull the card in, insert card vertical, and horizontal. How does one tell when something unusual is present?
From a technology standpoint, new machines are being built with the reader embedded deep within the machine; the slots on the machine are being designed to make it difficult to attach a skimmer or loop. Also, a new technology called 'jitter' forces the card to move back and forth, and at different speeds, while it is reading the information. That foils many skimmers, which require a smooth card reader. Consider the third image (operate page) with a fraud cover like in the second image in the operate page. These improvements will help, but with the number of older machines in use, the thieves will have an easy time finding susceptible targets for years to come. The first image on this page is an RF detector from ATM PARTS Company in the UK. This detector is set up for the NCR machines and is adaptable for other machines using methods described in the patent (last image).
