If your debit card has been skimmed, contact your bank immediately. Your bank will help you get a new account number and card. Be sure to check your original account to make sure no money has been stolen. Check your accounts. If personal information has been compromised, thieves may try to access other accounts you hold, pretending to be you.

What are the types of RFID tags? What products contain RFID tags? What is RFID used for? What is RFID skimming? Where does RFID skimming occur?
How can you protect yourself against RFID skimming? What can you do if you become a victim of RFID skimming? RFID tags can be passive or active. Here are a few ways to protect against RFID skimming. Implement access controls. RFID can form the basis of an effective asset management system and is also at the heart of the Internet of Things.
Here are some of the benefits of RFID:. Keeping track of assets and materials is a challenge for most organisations — whether it is components on a production line, finished products being despatched, industrial containers that need returning, or tools, laptops and other high-value equipment that often go missing. RFID systems offers a fast and reliable way to track them without having to count each individual item.
With RFID applications you can immediately see how many items you have of any one type and their location or what stage they are at in the process. You can track items from the time they are received into stores, issued to manufacturing and used in a finished item.
RFID can also help to find items that are on site but have been misplaced. RFID applications can automatically track the movement or goods and upload the information to the ERP or financial management system.
Therefore they can remove the need for manual form filling and replace outdated spreadsheets. The use of fixed readers at key points can save even more time — and on a production line for example, can remove the need for manual intervention entirely. The use of cloud-based systems allows everyone in the organisation to see up-to-date data on the whereabouts or status of items. Data can also be shared with customers. RFID systems allow companies to check when equipment and vehicles have been inspected or when inspecton is due, and restrict their use if certain conditions are not met.
Systems like CheckedOK offer an efficient way to manage inspection and reporting regimes and help satisfy insurers or regulatory bodies that processes are being followed.
Because RFID can identify individual items or components, it is ideal for complex or customised manufacturing processes — for example, to ensure that specific moulds are filled with the correct volume of liquids and fired for the correct period of time, or specific components end up on the right production line. This helps reduce waste and improve efficiency. RFID systems can also help ensure that items have passed through all the correct checks and processes — for example, a boiler has been assembled correctly and been inspected and approved before being delivered to the customer, thus improving quality and reducing the number of goods returned.
RFID tagging can help ensure traceability by tracking an item right from its point of origin. Fixed costs do not necessarily mean that you will not ever purchase that item again, it just means that the item is not used once and then discarded or consumed during the application.
If you plan to set up an initial system and then expand that system later, hardware will still be considered a Fixed Cost.
RFID tags are only considered to be a fixed cost when they are continually reused throughout the system — e. Recurring costs are attributed to items that are used once and then discarded or consumed during the application. Because of their low-cost, these tags are frequently applied once and kept on an item for its lifespan or discarded after use.
If an RFID printer is used, then printer ribbon would also be a recurring cost. If a software license renews annually or is purchased as a SaaS Software as a Service product, then it too should be factored as a recurring cost. RFID systems can be susceptible to certain materials and environmental factors that can cause diminished read ranges and affect overall system accuracy.
Metal and liquids are the two most common sources of interference for RFID applications, but they can be mitigated with the proper RFID tags, equipment, and planning. As UHF RFID becomes more commonly used with liquid-filled items or metallic items, more and more tags are released with new ways to lessen these problems. In addition, techniques have been developed that can help mitigate the effects of these items, like working with tag placement and spacers.
While each system will vary in terms of device types and complexity, every RFID system contains at least the following four components:. RFID tags typically do not have a battery unless specified as Active or BAP tags ; instead, they receive energy from the radio waves generated by the reader. Each of these memory banks contains information about the item that is tagged or the tag itself depending on the bank and what has been specified. Hundreds of different RFID tags are available in many shapes and sizes with features and options specific to certain environments, surface materials, and applications.
A common way to divide tags into types is inlays vs. Tag pricing depends on the type of tag and the quantity that are being ordered. The higher the level of customization or the more specialized the tag, the more expensive it will be in comparison to typical off-the-shelf tags. Readers, also called interrogators, are devices that transmit and receive radio waves in order to communicate with RFID tags.
Fixed readers stay in one location and are typically mounted on walls, on desks, into portals, or other stationary locations. A common subset of fixed readers is integrated readers. An integrated RFID reader is a reader with a built-in antenna that typically includes one additional antenna port for the connection of an optional external antenna as well. Integrated readers are usually aesthetically pleasing and designed to be used for indoor applications without a high traffic of tagged items.
Mobile readers are handheld devices that allow for flexibility when reading RFID tags while still being able to communicate with a host computer or smart device. There are two primary categories of Mobile RFID readers — readers with an onboard computer, called Mobile Computing Devices, and readers that use a Bluetooth or Auxiliary connection to a smart device or tablet, called Sleds. Fixed RFID Readers typically have external antenna ports that can connect anywhere from one additional antenna to up to eight different antennas.
With the addition of a multiplexer, some readers can connect to up to 32 RFID antennas. The number of antennas connected to one reader depends on the area of coverage required for the RFID application. Some desktop applications, like checking files in and out, only need a small area of coverage, so one antenna works well. Other applications with a larger area of coverage, such as a finish line in a race timing application typically require multiple antennas to create the necessary coverage zone.
The most common way to categorize readers is to classify them as either fixed or mobile. Other ways to differentiate between RFID readers include categories like connectivity, available utilities, features, processing capabilities, power options, antenna ports, etc.
