# Biblio::RFID::Reader::3M810(3pm)

support for 3M 810 RFID reader

## NAME

Biblio::RFID::Reader::3M810 - support for 3M 810 RFID reader

## DESCRIPTION

This module uses Biblio::RFID::Reader::Serial over USB/serial adapter with 3M 810 RFID reader, often used in library applications.

This is most mature implementation which supports full API defined in Biblio::RFID::Reader::API. This include scanning for all tags in reader range, reading and writing of data, and AFI security manipulation.

This implementation is developed using Portmon on Windows to capture serial traffic \<http://technet.microsoft.com/en-us/sysinternals/bb896644.aspx\>

Checksum for this reader is developed using help from `"selwyn"` \<http://stackoverflow.com/questions/149617/how-could-i-guess-a-checksum-algorithm\>

More inforation about process of reverse engeeniring protocol with this reader is available at \<http://blog.rot13.org/rfid/\>

### afi\_retry

This specified how many times will driver try to write afi to tag

```
  Biblio::RFID::Reader::3M810::afi_retry = 100;
```
