WIKI – Frequency, Chips, Protocols and standards explained 👨‍🏫

Pilgrimsmaster · November 23, 2019, 9:26pm

Hi Lounge team, I am thinking about making another WIKI, with a level up explaining as the title says. Before I spend any more time on it, Let me know if you think it is worth pursuing, and feel free to add suggestions or edit as you see fit! Still A LOT of work to do on it, this is just a placeholder for living document.

The goal of this Wiki is to condense the information contained within, for the beginner to intermediate user, to expand their further understanding of Chips, Protocols and Standards used in implants.

ANATOMY OF AN IMPLANT

xSeries
cylindrical sterile bioglass implant

x-series chips have a cylindrical coil antenna wrapped around a ferrite rod encased in biosafe resin
I WILL ADD NICER ARROWS AND LABELS TO DIAGRAMS
Chip, antenna, enclosure etc

And hopefully a higher Res Photo

Flex Series

flexible biopolymer package

coated in USP Class VI, ISO 10993 tested biopolymer which gives it an extremely thin profile and semi-flexible structure

PRODUCT MATRIX

DISCOURSE HANDLES TABLES WEIRDLY, I WILL NEED TO WORK ON THIS
Dangerous Things Website has a more detailed and Informative Product Matrix
Image as an example

*CHIP SPECIFICATIONS*

T5577

(ATA5577C) also referred to as t557x on the Proxmark

T5577 is an RFID chip that can emulate many different types of 125kHz chip types
EM41xx,
EM4200,
HID 1326
ProxCard II,
HID 1346
ProxCard III
Indala
AWIA.
The T5577 does not support “tear protection”
The T5577 has password protection functions to block reconfiguration by accident or malicious attack.

NTAG216

7 byte UID and 886 bytes of user read/write memory
10 year data retention. Rated for 100k writes per memory block.
Data Sheet

S50

S50 Mifare Classic S50 1K chip. This chip type is ISO14443A compliant but is not NFC compliant
xM1 13.56mhz S50 (Mifare Classic 1K)

The xM1 is a high frequency 13.56MHz transponder based on the Mifare Classic S50 1K chip. This chip type is ISO14443A compliant but is not NFC compliant. The xM1 has 768 bytes of user programmable memory and also supports Crypto1 security features. The xM1 is supported only on some NFC devices which contain a reader chip from NXP. While the xM1 will work with any ISO14443A reader, including our PN532 reader, it cannot be expected to work reliably with all NFC devices. We supply the xM1 for people who have a specific need for this particular chip type.

*PROTOCOLS*

NFC – Near Field Communication is a set of communication protocols

( NDEF ) NFC Data Exchange Format is a standardized data format that can be used to exchange information between any compatible NFC device and another NFC device or tag. The data format consists of NDEF Messages and NDEF Records

All of the HF implants are NFC compliant with the exception of the M1 family ( xM1, FlexM1 gen1a, FlexM1 gen2 )

Mifare S50 1K tag is also a passive RFID tag that also operates at 13.56MHz and is also ISO14443A, but it is not NFC compliant

*STANDARDS*

ISO - International Organization for Standardization ( French )

EM4102
ISO14223 ISO11784/85 Animal ID and ISO 18000-2 AIDC
ISO11784/5
ISO15693 – Vivokey Spark (Original)
ISO14443A
