About this deal

For 125 kHz chips, the usual reading format is a 10-digit decimal number, but other formats are popular as well. Some MIFARE® chip readers read by default read the ID in a format 8-digit Hexadecimal (8 HEX), but we saw many applications which use the 8 HEX reverse byte format as well. NFC devices like mobile phones and tablets read the ID code in the 14 HEX Reverse byte format.

There are a number of different frequencies used in Access Control methods, and you can get readers which combine these together or readers which use these separately. A very common frequency, 125 KHz, is classed as a low frequency and enables a great read range of up to 1 meter in the ideal conditions, however this low frequency technology can only transmit small amounts of data. A perfect choice for these kind of low frequency RFID Cards can be found within the HID Proximity Card and SwiftProx Card range.

RFID technology allows businesses to encode data on small chips attached to a plastic card. This can then be used for access purposes, with the card transmitting identification data to an external receiver. As of 31 October 2014, regulations are in place in 78 countries representing approximately 96.5% of the world's GDP, and work on regulations was in progress in three countries representing approximately 1% of the world's GDP.

There are contradictory opinions as to whether aluminum can prevent reading of RFID chips. Some people claim that aluminum shielding, essentially creating a Faraday cage, does work. [140] Others claim that simply wrapping an RFID card in aluminum foil only makes transmission more difficult and is not completely effective at preventing it. [141] What's New".

RFID Cards and How Do They Work? | Swype What Are RFID Cards and How Do They Work? | Swype

New York's award-winning traffic control system". ITS International. January–February 2013 . Retrieved 3 May 2014. A group of tags has to be illuminated by the interrogating signal just like a single tag. This is not a challenge concerning energy, but with respect to visibility; if any of the tags are shielded by other tags, they might not be sufficiently illuminated to return a sufficient response. The response conditions for inductively coupled HF RFID tags and coil antennas in magnetic fields appear better than for UHF or SHF dipole fields, but then distance limits apply and may prevent success.
