yeah, you used to be able to damage the chip on 201 cards in the UK anyway and it used to revert to signature, you also used to be able to change the 2 into a 1 on the track and it used to work aswell. But now no good, your best bet in regards to carding with 201 dumps, is use in countries like the U.S etc where they still use magstripe. Most if not ALL of the EU is 201 terminals so u need card and pin. But alot of U.S dumps work in europe you just need to find the right ones, i know them

.
Also i had no problem using UK 201 dumps in the US, for amounts up to around $2000. It never even went for authorisation call.
A Very good method for carding i have found in the US not so good in the UK because shops are scared of any transactions that involve your chip+pin due to liability issues. But anyway if you have ability to emboss cards then buy CVV info and emboss card number/exp/CVV and name.
If possible emboss card with blank CHIP on it for effect, when the shop goes to swipe obviously their is no info on magstripe so in countries like US the only fallback method is to KEY in the long card number, then if it goes to auth u can take the call if u have DOB, Billing, Mothers Maiden, SSN etc, etc.
This is a very good method i have found and i have carded in UK, US, France. Primarily for mid-high value transactions, especially if u spent time with the mark negotiating thr sale most places will be reluctant to let a lucrative sell go especially if they have put work in.
