My M400 isn’t reading chip cards, what do I do?

Your Semi-Integrated M400 accepts EMV cards. If your Semi-Integrated M400 is not reading a chip card, check that the card is fully inserted into the card slot.

If the card is fully inserted, but still is not being read, complete the following steps:

1. Remove the card from your Semi-Integrated M400.
2. Contact your POS provider to confirm that the integration between your POS and your Semi-Integrated M400 is up to date.

If your POS integrator confirms your integration is up to date but your Semi-Integrated M400 still isn’t reading chip cards, contact our
Support Team.
