Figuring out NFC bike lock


#1

Hey guys,

So I ordered the egeetouch padlock from this post here:

Here is the product’s amazon page:

Combined with a simple chain I already have, I’m going to use this as a bike lock via my xNT implant in my left hand. The lock works with the nfc tags it comes with, now just need help on how to use my xNT as a key.

I use NFC Tools Pro to manage my implant, and am able to scan / read / write the tags that came with the lock. Using the copy tag function, I scan the egeetouch tag, and then scan my hand to paste. Unfortunately, I get a “write error!” message.

Does anyone know the solution?

You can’t copy tags to the xNT. The UID is fixed and can’t be changed.

What you’ll need to do is to add the UID of your xNT to the lock, and not the other way around. I’m not sure how you add new tags to that specific lock, but the link you provided says “Multiple Fobs can be used to unlock one lock and easily set them using the App”, so you’ll probably need to look into the app made for the lock.

@jhurley14 by any chance, did you try adding your xNT to the lock? If so, did that work out for you?

I’d love to be able to lock several things with such a lock but really hope it’s compatible with my xNT.

I’ve also found significant variances in antenna performance with eGee products… so it may just not be coupling :confused:

I am also trying to use my XNT with an egee padlock… not sure if it’s going to work. The padlock app allows you to add new tags with seemingly somewhat arbitrary IDs… but there are only 4 characters available to type the ID into the app. The XNT has a 7 byte UID… so I’m thinking the padlock might only work with 4 byte UIDs. I’m not sure if there’s a way for me to translate some or all of my UID into something that I can enter as 4 characters… translating to ascii creates pretty odd characters…

Figured this out by scanning a factory tag. It ships with 7 byte uid tags, but only uses bytes 1, 2, 3 and 4 of the uid to pair.

So I entered in those bytes from my xnt, and I think it should work, but I think I’m having read issues as @amal mentioned. Even using the xled it’s really quite hard to get it to flash. Maybe with some fresh batteries it’ll work… Seems like a better padlock is needed.
