How close was the card to the antenna, I have noticed a problem when I have my card direct on antenna but with distance it becomes good again

[Defensor7]

No result at any distance. HID card works. Em Marine card does't.

Last Iceman's fork works well.

[RfidResearchGroup]

Try latest source., same as #3

[RfidResearchGroup]

@Defensor7 have you had the chance to test?

[Defensor7]

Yes, it works now.
