Dennis is correct, the liability shift moves over in October to the merchant. EMV cards will still have mag strips so you will still be able to take them but if one is fraudulent you will lose. The reason for the delay is in part because MC and Visa could not decide on whether it would be chip and PIN or chip and signature. I think Visa is chip and PIN and MC is chip and signature. Chip and pin in a restaurant means you will need to bring the reader to the customer or have them come up to the counter. This adds a huge cost to full service restaurants.
No idea why Aloha isn't telling their dealers what to do yet. If you want to skip the Aloha software and use a third party, look into Shift 4. There are a few others out there that handle the CCs outside of the POS and in the backend, they send down payment info so it still is integrated.
Another option, Ziosk or E La Carte order at the table tablets also have payment integration. Using them, you also would get all the benefits that ordering at the table has.
