HID Prox
HID Prox is a proximity card format developed by HID Corp. HID Prox cards operate on a frequency of 125 kHz. Cards of this type are for use only with HID readers and HID-compatible readers (such as the appropriate models from the RF IDeas pcProx range) designed to read 125 kHz cards.

HID iCLASS™
HID iCLASS™ is a proximity card format developed by HID Corp. HID iCLASS™ cards operate on a frequency of 13.56 MHz. Cards of this type are for use only with HID readers and HID-compatible readers (such as the appropriate models from the RF IDeas AIR-ID range) designed to read 13.56 MHz cards.

Indala Prox
Indala Prox is a proximity card format developed by HID Corp (formerly Indala, which HID Corp took over). Indala Prox cards operate on a frequency of 125 kHz. Cards of this type are for use only with Indala readers and Indala-compatible readers (such as the appropriate models from the RF IDeas pcProx range) designed to read 125 kHz cards. Note that Indala cards are available both in open and custom format.

MIFARE® is a proximity card format developed by Philips. MIFARE® cards operate on a frequency of 13.56 MHz. Cards of this type are for use only with proximity readers which can handle the MIFARE® format.

MIFARE® Classic 1K
MIFARE® Classic 1k cards store 1k of information divided into 16 sectors of 4 blocks (each block contains 16 bytes). The last block of each sector is used to store the access keys and conditions; also the first block of sector 0 (the sectors are numbered 0 to 15 and the blocks 0 to 3) is used to store the card serial number (CSN) and other identifying information. Therefore, the amount of space used to store application data is in practice 752 bytes.

MIFARE® Classic 4K
MIFARE® classic 4k cards store 4k of information divided into 40 sectors; the first 32 are of 4 blocks, while the last 8 are of 16 blocks. As with the 1k card, the last block of each sector is used for access control, while the first block of sector 0 is for the CSN. The amount of space available in practice on the card is 3440 bytes.

SLE4404
SLE4404 is a contact card format developed by Infineon. Cards of this type are for use only with contact readers which can handle the SLE4404 format.

SLE4442
SLE4442 is a contact card format developed by Infineon. Cards of this type are for use only with contact readers which can handle the SLE4442 format.
