The chip in my UK passport failed to work when I recently re-entered the UK. I have two queries about this.

1) Is there any convenient way of checking whether the chip is actually functioning correctly?

2) I wish to travel to the US soon. If the chip is not working, is it essential to get a new passport in order to be admitted to the US? Apart from the matter of the chip, my passport is not damaged visibly in any way.

    Failed to work at the e-passport gate, or the immigration officer commented when admitting you that the chip wasn't working? (They're quite different)

If you have an NFC-capable phone, you can get an app which scans a passport's chip. I've tested it successfully on my New Zealand passport. Even if the data is encrypted, at least you'll know it's scanning correctly.

Android example: NPC Passport Reader
