RFID Chip

The tool has an embedded RFID chip which stores information about the product. The chip is located on the motor of the tool. With an RFID reader it is possible to read and write information to the chip.

EPC Memory

Product number, generation letter and serial number of the tool are stored in the EPC memory of the RFID chip. The information is presented as a 20-character-long string.

Example

String stored in EPC memory: 84366130150670730145

The string reserves three characters for the generation letter, which is presented in ASCII format. As the ASCII codes of the generation letters only use two characters, a “0” is always added in front of the ASCII code.

The table below shows the generation letters with corresponding ASCII codes.

Generation Letter	ASCII Code	Generation Letter	ASCII Code
A	65	N	78
B	66	O	79
C	67	P	80
D	68	Q	81
E	69	R	82
F	70	S	83
G	71	T	84
H	72	U	85
I	73	V	86
J	74	W	87
K	75	X	88
L	76	Y	89
M	77	Z	90

The EPC memory is writable which enables the chip information to be reprogrammed in cases where the motor from one tool is to be reused in another tool.

User Memory

Apart from the tool information in the EPC memory, the RFID chip also contains a 512-bit user memory, available for the customer to add any additional information.
