In 2018–2020, law enforcement (Europol, Secret Service) conducted “Operation Night Wire” and similar actions, seizing thousands of pre-loaded counterfeit chip cards. Analysis showed many criminals used JCOP Manager or SmartCardPe (often labeled “v8.6” after modification) with compromised dumps from POS skimmers. However, success rates were low (under 12% at EMV-enabled POS) unless the terminal was intentionally misconfigured.

The evolution from v8.6 to current-generation reader/writer tools mirrors the broader security arms race. EMVCo responded to the rise of easy-to-use writer software by mandating: emv reader writer software v8.6
In turn, newer "v8.6-like" tools have adapted by adding relay attack modules (NFC relay, or ghost-and-leech) rather than purely write-based cloning. The software now often includes scripts to emulate a card over Bluetooth to a real terminal, proxying to a genuine card held miles away.
