What is T5557 card?

What is T5557 card?

Description. T5557 cards are read/writable and are compatible with EM4100, HID and indala. The card operates at 125kHz. 10 cards are included per order.

Can RFID cards be rewritten?

Microchips in RFID tags can be read-write, read-only or “write once, read many” (WORM). The information on such chips can never be changed. WORM tags can have a serial number written to them once, and that information cannot be overwritten later.

Is NFC and RFID the same?

NFC stands for Near-Field Communication. NFC is also based on the RFID protocols. The main difference to RFID is that a NFC device can act not only as a reader, but also as a tag (card emulation mode). NFC systems operate on the same frequency as HF RFID (13.56 MHz) systems.

Can Iphone read RFID card?

Yes there is a RFID dongle that is compatible for iOS devices.

How do RFID cards store data?

Data is typically stored in user memory on a tag. This is separate from the field for the unique serial number, which can be pre-programmed or assigned by a user.

Is RFID the same as NFC?

While RFID technology can be used over long distances, NFC technology is limited to small distances. RFID tags can generally be scanned at distances of up to 100 meters and do not require a direct line of sight to the reader.

How does the t5577 RFID card work?

The antenna and chip together form an inductive card or tag. The chip of T5577 RFID card has a 330-bit EPROM (distributed in 10 blocks, 33 bits per block) that can be read/written from the T5557 card reader. Block 0 is a parameter configuration block that is reserved for setting the T5557 operating mode.

What is a t5557 card?

The T5557 card is a multi-function and contactless R/W identification IC manufactured by Atmel Corporation of the United States for the 125 KHz frequency range.

How many bits is the Atmel t5557?

T5557 Read/Write RFID Transponder The Atmel T5557 is a 330 bit Read/Write RFID transponder operating in the 125Khz band. Its memory is structured in 10 blocks of 33 bits, however only 224 bits are available for storage and retrieval of user defined data. This is structured as 7 blocks of 32 bits of read/write data.
