RFID (thing)

Problems with RFID

• Distance
  
  • Many tags, especially cheaper ones can be read from only a few feet away. 
    
• Disruption
  
  • Tags are easily disrupted.  In credit cards it can be as simple as taking a hammer to the back of the card. 
    
  • Most signals can be blocked using aluminum. 
    
  • Radio signals can be diverted, reducing the distance of the reader
    
• Price
  
  • For many products and applications the cost of RFID is simply too high to be a profitable business venture. 
    
• Security Risks
  
  • There are issues regarding RFID security.  The main concern is that a person could hypothetically be tracked by anyone with a tracking device.  This poses a privacy risk. 
    
• Standardization
  
  • There is no current global standard for the tags
