What is RFID?

What is RFID?

  • Q: What is RFID?

    Answer: RFID is a small circuit integrated into your ticket, or season’s pass. When you pass through the lift line, this circuit will register and open an access gate automatically.

  • Q: Why is Mammoth Mountain Using RFID?

    Answer: There are many guest benefits that RFID allows Mammoth Mountain to provide. Benefits include Direct-To-Lift access, reloadable tickets and easier access to the mountain and lifts.

  • Q: What information is stored on Pass/Ticket RFID Cards?

    Answer: Each RFID tag physically contains only the randomly generated number associated with each unique user profile. No personal or additional information is stored on individual RFID tags.

  • Q: I've seen scanning at other resorts, is RFID better?

    Answer: RFID and bar code scanning achieves the same goals though different means. Bar codes require line of sight so that that each ticket or pass can be read by a scanner. RFID is read via an embedded passive radio frequency chip and does not require a line of sight. This means you will not have to show your pass/card/ticket each time you load the lift.

  • Q: Can RFID be used to access my personal information?

    Answer: Each unique RFID tag contains a multiple digit number randomly associated with a user profile. This profile is kept as a secure component of our point of sale system and user database, and will not be accessible to other guests or employees.

  • Q: Will my RFID Pass/Card interfere with other RFID products?

    Answer: No; because each RFID tag is associated with a specific randomly generated number that is associated with a specific, secure database, other RFID products will not register within the Mammoth Mountain lift access system. Other RFID products currently in use include the Expanded CA Drivers License, US passports issued since October 2006, and many current makes and models of alpine ski and snowboard equipment.

  • Q: What About RFID & Pacemakers?

    Answer: Electronic devices (e.g. radio units, mobile phones, security systems, etc.) create electromagnetic waves of different frequencies and intensities. These are caused by the design of electronic devices and therefore in most cases cannot be avoided. Unfortunately, these waves sometimes may also lead to an undesired impairment of other sensitive electronic devices. 

    Mammoth's Axess/Sirius lift access system is CE certified and complies with all standards. It was found that with the proper use of devices there is no danger for persons using pacemakers when passing hands free entry systems at the lift. However, for general reasons of precaution and compliance with the general requirements applicable, the general recommendations for using electromagnetic units should be observed and the following rules should be adhered to:


    *Guests with pacemakers must not wear their lift access media cards near the heart when passing through the gate and a distance of 8 to 12 inches should be observed in the case of queues and while passing through the gate.

    *If you prefer not to pass through the gate, please alert our validation staff at the lift and you will be given alternative direction for lift access.

    *If vertigo or sickness is experienced, get out of the direct vicinity of the gate or device.


  • Q: Are there any other concerns associated with RFID?

    Answer: Mammoth Mountain is employing Passive RFID technology which does not radiate any RF energy, but simply reflects it. As a result, the passive RFID tags used at Mammoth Mountain do not contribute any additional RF energy into the surrounding environment.

  • Q: Can I Punch A Hole In My RFID Media Access Card?

    Answer: No, holes must never be punched in the access media cards - season passes and daily lift tickets. The card has an antenna embedded that surrounds the embedded RFID chip. Any damage to the surrounding antenna will render the card inactive and must be replaced for a replacement fee.

  • Q: Can a magnet destroy an RFID tag?

    Answer: No. The chip information is not stored magnetically. Use of a magnet or other erasing devices has no effect whatsoever on the chip.

  • Q: Can chips 'survive'; in pieces of clothing, washing machines and dryers?

    Answer: Yes. RFID chips are designed in such a way as to survive normal wear and tear for years, washing and drying included. We even know of at least one lender of uniforms in the USA who employs RFID in order to keep track of their inventory and assignments after cleaning. That means that the chips even withstand industrial standards of use and cleaning.

  • Q: How widely used is RFID technology?

    Answer: RFID technology is used in wide variety of industries and applications. Your automobile almost certainly has an immobilizer to prevent it from being stolen. It has been ten years since the Ford Motor Company first introduced an RFID immobilizer and such systems are common in vehicles manufactured by the other major manufacturers. RFID has also been used extensively in toll collection, inventory control, building security, and library systems.

  • Q: Will RFID technology interfere with my other wireless technology?

    Answer: The radio frequencies used by RFID are assigned by regulatory agencies around the world to help ensure that no interference occurs.

  • Q: Can RFID be read from Satellites?

    Answer: No. Because of the short read ranges of RFID and the huge amount of power that would be required to broadcast from a satellite in order to pick up information on each RFID tag, satellite read is not practical nor possible.

  • Q: I'm buying a pass for a child, grandchild, or friend, how do I do this?

    Answer: You will be able to purchase these products online. The parent/Guardian (over 18) must build their profile first. The information for the pass holders is entered later in the process.

  • Q: Where should I carry my RFID access card?

    Answer: You must put your RFID access card in a separate pocket from things such as: cell phone, iPod, or any foil wrapped items such as gum wrappers, cold medicine etc.
