I found this, Bought it, Tested it, and below is my review.
TESTING INCLUDING READ RANGES
- Fresh Battery (CR2)
Works with
The range was contact and difficult to get a read, but I believe this was due to the sensitive touch pad, as the keypad was activated as soon as it is touched
I’ve tried foam, plastic and rubber to seperate skin contact.
xSeries were not able to be read
TEARDOWN
I may do this later, and see if the antenna is possible to move closer
