HID cards use the same technology as Radio Frequency Identification (RFID) tags. However, HID codes can be printed while RFID codes cannot.

The Basics
A small and cheap printer can be used in printing HID codes. This makes it possible for companies to print their own passports, wearable security badges, door access card readers, and automatic PC login cards. For authorization, a reader has to read the code and consult a database. The database can be adjusted as the status of HID changes.

Typical Uses
Most HID cards are read with normal card readers. HID card data can be analyzed with a hid card reader wiring diagram. Some of the cards operate on proximity, hence the name proximity card. This means that the cards can be read if they are within 2 feet from the reader. This feature allows workers to automatically access their work spaces by walking through a door that has a reader.

HID cards are easy to read in some cases, which raise security concerns among many users. In some instances, hackers have gained access into HID security systems by using simple hardware that operates on similar frequencies as users’ HID readers.

Proximity ID vs. RFID
Proximity identification (ID) and RFID use the same technology. However, proximity ID is mainly a security solution while RFID is mostly used in the shipping industry. The vital component of both technologies is radio waves.

The term RFID is used to refer to different technologies that rely on radio waves to identify people or object. RFID tools can be used to recognize items and people. The data collected by RFID can be stored in a microchip connected to an antenna. The process is called a RFID tag. The RFID technology is mostly used for tracking containers and packages in the shipping industry. RIFD is also used to keep track of supply in warehouses. The work of the chip is to transmit the ID information to a reader.

Proximity ID
Proximity ID is also known as contactless ID card or a proximity card. The cards communicate with a remote server using an embedded antenna. Proximity cards are read only devices used as security cards to access secured doors.

You can use a battery to boost the read range of a RFID tag to up to 300 feet. However, a proximity card can read from only 2 feet away. In addition, a proximity card holds less data than an RFID tag.
