Mifare Hotel Lock VS Temic Hotel Lock, What's Difference and How to Choose?

RFID (Radio Frequency Identification) technology has been widely used in the hotel door lock system and industry. RFID non-contact key cards (room cards) have replaced the original mechanical keys to enhance the customer experience. After more than 20 years of rapid development, almost all hotels now use contactless RFID hotel door locks.

There are two main types of RFID card hotel locks:  125Khz Temic hotel locks and 13.56MHz Mifare hotel locks, but many customers may not know the difference between the locks and don't know how to choose the suitable hotel locks.

This article will explain the differences, advantages, and disadvantages of the two types of hotel locks. To help customers better choose the appropriate hotel lock system from function, demand, and cost.

1. Overview:

Mifare hotel lock----- Use Mifare cards. The frequency is 13.56Mhz.

Temic hotel lock----- Use Temic card, frequency 125Khz.

2, What's the difference between Mifare hotel lock and Temic hotel lock

Extended usage and functions:

  • Just because the Mifare hotel locks use Mifare cards, and Mifare cards are not only used in hotel locks but are also widely used in all-in-one card access systems, door opening, access control, consumer systems, etc.
  • If your hotel uses a Mifare card hotel lock system, then the Mifare cards can be used as a room card to open the door lock and can be used on the access control system of other areas of the hotel. For example, if your hotel has restaurants, bars, gyms, etc., you can ask your hotel guests to use this Mifare room card to enter and spend.
  • Hotel elevator control system: At the same time, if your hotel has an elevator and wants to allow hotel guests to enter and use the corresponding floor through the hotel room card, then the Mifare card hotel lock system will be the first choice.
  • Temic cannot be used in all-in-one card systems. It can only be used as a hotel room card to open the room door.
  • Hotel energy-saving. Although both Mifare cards and Temic cards can be used in the hotel room's energy-saving switch to power the room, only the energy-saving switch that supports the Mifare card can only use the corresponding room card to supply power. You need to know that most hotel rooms' energy-saving switches can be accessed by inserting credit cards and other cards.

Data collection:

Suppose the hotel needs to collect the door opening and closing date from the hotel lock. The Mifare card hotel lock system only needs to use the Mifare 4 S70 card to obtain the MIFARE hotel lock data, but the Temic hotel door lock should be collected using a data collector.


For hotel applications, the Mifare 13.56MHz RFID hotel lock will be better than the Temic hotel lock regarding security, reliability, and system scalability.

  • MIFARE card is currently the world's most used inductive smart IC card with the most mature technology and the most stable performance.
  • Strong anti-interference ability. There is a fast anti-collision mechanism in the MIFARE card, which can effectively prevent data interference between cards when multiple cards enter the read-write range at the same time.
  • The storage structure and characteristics of the MIFARE card (large capacity-16 partitions, 1024 bytes) have robust system application scalability and can genuinely achieve "one card with multiple uses."
  • The reading and writing of the data recorded in the Mifare card require corresponding password authentication. Even each area in the card has different password protection to protect data security fully.

Working and reading distance:

Simultaneously, in the actual use of RFID hotel door locks, the working distance of the Mifare and TEMIC room key (card) is different.
Since most hotel door locks, the primary material used for hotel door locks is metal, except for the front and back sides, the antenna will be surrounded by metal, and metal will attenuate RF signals. The 125KHz and 13.56MHz RFID signals will be affected.

In this environment, the higher frequency (13.56MHz) can still maintain an acceptable working distance within 3-5cm, which is better than 125KHz (only 1-2cm left).

4, Please Noted: 

And the entire RFID hotel door lock system usually includes four essential elements: RFID hotel locks, RFID guest room cards, RFID card encoders, and hotel lock system management software. These four elements are interrelated and crucial.

The hotel lock (main PCB), RFID room card, management software, and room card encoder in the RFID hotel lock system must be compatible with each other. And these products must come from the same manufacturer or supplier as much as possible;

Otherwise, they will not work. Because different manufacturers or suppliers have their encryption methods to encrypt these products, for example, you cannot use a hotel lock from one manufacturer but use software and encoders from another manufacturer.
