SL3S1003_1013 RFID padlock tamper seal

Question asked by Yoko Kurokawa on Jun 21, 2017

To whom it may concern,

 

My name is Yoko Kurokawa from SEIKODO Corp., Japan.

We ordered 100 non-encoded RFID padlock tamper seals with William Frick &

Co. before.

They told us that here is the datasheet for the chip which is used in this

RFID padlock tamper seal.

http://www.nxp.com/documents/data_sheet/SL3S1003_1013.pdf

So we'd like to ask you the following because the chip is from your company.

 

We encoded some of them with the writer machine by ourselves.

Some RFID padlocks changed the encoded number after we teared the wire but

other RFID padlocks didn’t change the encoded number even after we teared

the wire.

Please see the attached as for the details.

We think that the encoded number should change after the wire was teared,

but some won’t change.

Please tell us the right way of encoding if ours is wrong.

And we want to know how the encoded number changes.

 

We await your reply.

 

Regards,

Yoko Kurokawa & Kaori Kutsumizu
