POS auf EMV-Chip & kontaktlos umstellen: Haftungsverlagerung, Lesertypen und die Migration

If a till still relies on swiping the magnetic stripe, it’s carrying fraud liability, running on a technology the card networks are retiring, and asking customers to do something slower than the tap they now expect. Upgrading to EMV chip and contactless fixes all three — and often only the payment device needs to change. The case in brief:

The stripe and the chip carry the same card data very differently — and that difference is the whole security story:

Contactless is EMV too: a tap runs the same chip-grade cryptography over NFC in about a second. So “chip” and “tap” aren’t rival technologies — they are two ways to use the same secure EMV rails, and a modern reader supports both.

Two policy forces make this an upgrade with a deadline, not an optional nicety:

When you choose an acceptance device, the goal is one reader that covers every card a customer might present:

The four checks that decide whether a reader will actually work for you:

A clean migration path from swipe-only to chip + contactless:
