Wanted to share a note that First Data has communicated to us that retailers can no longer use the PAX MT 30 payment terminals as of August 1st, 2019. A good replacement option is the PAX S300.
I suspect that other processors like TSYS, Heartland, etc will soon follow suit and set a deadline for PAX MT 30 payment terminals to be replaced.
This is due to PAX no longer offering compliance updates for the PAX MT30 payment terminals.
If you are using the PAX MT30, be sure to contact your credit card/merchant services salesperson for options.
