= Reading all the tags =

Someone already wrote a program and made a simple instruction for building the hardware that lets you read every type except for the "Avid Encrypted" tags, which can be read but not decrypted. They also put a web API online for decrypting the Avid Encrypted tags and they have instructions for how to build your own decryptor. Everything is [http://max-gpl.sourceforge.net/ here].

= Standards and "Standards" =

All chips operate at either 125 kHz (ISO) or 134.2 kHz (proprietary) but a scanner using either frequency can read both types:

<blockquote>
Although ISO chips are optimized for 134.2 kHz, in practice they are readable at 125 kHz and the "125 kHz" chips are readable at 134.2 kHz.

== ISO 11784 & 11785 ==

Includes half-duplex (HDX) and full-duplex (FDX) types. I've seen references to FDX-A and FDX-B but unsure of the difference.

Readers retail for ~$150 on ebay.

== Trovan ==

Also known as Trovan Unique. Also used by some HomeAgain chips and Bayer chips.

== FECAVA / Destron ==

Used by:

* Avid EuroChip
* 24PetWatch
* Original HomeAgain chip

== AVID Friendchip ==

Also known as Avid Encrypted.
