RFID Reader

This software supports the TI S6350 module for use as a RFID reader. The Core Speedway lap counter uses this module.

Standard 13.56MHz ISO15693 tags should work.

Documentation on the TI S6350 module along with a Windows example program can be downloaded from TI's site here:

ISO 15693 Protocol

ISO15693

For communication with the reader we are using the standard ISO15693 protocol instead of the proprietary TI Tag-IT protocol. Documentation about this protocol can be downloaded from here:

 ISO15693 serial protocol

The full standard including electrical and physical characteristics can be downloaded from here:

 ISO15693 complete protocol

Software implementation

In order to use the TI reader within RealBasic we had to implement some of the serial protocol ourselves. In order to use the TI Reader with the ISO 15693 protocol you must first generate a command encapsulated in the TI protocol and have the payload of the command be the ISO 15693 command. Only 3 of the commands are necessary, Inventory All Slots, Inventory 1 Slot and Silence.

RFID Tags

The following tag can be used with the TI S6350 module:

 TI HF large rectangle transponder

It can be purchased from Mousere here:

Other standard tags should work.
