Contactless RFID chip cards are used as standard in the hotel industry, optionally also in combination with common magnetic stripe technology. With IDTRONIC key cards, you can manage guest management efficiently and without contact.

The data carrier is based on a transponder or chip which is connected to an antenna. An electromagnetic field generates the energy required to read, store and transmit information through the antenna of the transponder.

The contactless cards from iDTRONIC offer many advantages due to their unneeded physical connection to the reader. The communication is done by the electromagnetic field between the reader and the contactless card. They have a long lifetime and are insensitive to dirt and humidity.

Segmentation makes it possible to integrate different applications (e.g. access control to hotel rooms and e-payment services for vending machines or the hotel’s own wellness area) in a single card.

The use of the following chip technologies is recommended in the hotel sector:

  • MIFARE Classic EV1 – 1k / 4k [HF | 13,56 MHz | 1024/4096 Byte]
  • EM4200 [LF | 125 kHz | 8 Byte, read-only]
  • TEMIC [LF | 125 kHz | 28 Byte]

If required, we can also provide the cards with magnetic strips in the usual variants:

  • LoCo (mit 300 Oe)
  • HiCo (mit 2750 Oe)
  • Super HiCo (mit 4000 Oe)

The key cards can be printed with your desired layout using a high-quality offset printing process. Furthermore you have the possibility to equip the cards with serial numbers and/or UIDs for an exact user identification. In addition, the key card can also be punched for attaching to a lanyard or key ring.
