EEC/UK digital tachograph card

I have two years EU experience, but I’m “new and wannabe” in the UK.

I spent the last three years in Ireland, but not as a driver. My question is about the digital tachograph card.
My current one has been issued in Ireland, just a couple of months ago. Can I use it here in the UK, or do I have to exchange it again? I mean the technology (chip) is the same, right?
Anybody here who drives for a UK company but with EEC issue card?
