N.M. Stat. § 58-16-5
Point-of-sale terminals.
A. Subject to the provisions of Subsection B of this section, a POS terminal may be
used to perform internal business functions in addition to all functions defined as POS
transactions.
B. In conjunction with the performance of any POS transaction, the transfer or
deposit of funds to the account of a merchant or to an account held for the merchant, is
prohibited unless the account is maintained in an in-state financial institution having its
main office or manned branch in New Mexico.
C. A POS terminal shall not be operated to perform any POS transaction except
pursuant to a written agreement between the merchant on whose premises the POS
terminal is located and an in-state financial institution having its main office or manned
branch office in New Mexico, unless otherwise permitted or restricted by applicable law.
D. A merchant may designate specific POS terminals on its premises at which only
a limited number of particular POS transactions shall be performed.
E. The POS terminal shall be manned or operated by one or more individuals who
are agents, servants or employees of the merchant upon whose premises the POS
terminal is located, either alone, in cooperation with the cardholder or by the cardholder.
Provided, however, that an employee of a financial institution may be stationed at or
operate a POS terminal only for demonstration or training purposes or to verify its
accuracy.
F. A merchant contracting for any financial service functions through a POS
terminal shall make that POS terminal available to any other requesting in-state
financial institution, to the extent that the financial institutions are permitted by law to
engage in POS transactions. Provided, however, that the mandatory sharing of the POS
terminal will be upon the same terms and conditions of the written agreement between
the merchant and the financial institution originally initiating the written agreement.
Provided further, that any financial institution requesting to share a POS terminal shall
pay reasonable compensation to the originating financial institution as they shall agree.
G. At the end of each POS transaction, the POS terminal shall issue the cardholder
who initiated the POS transaction a receipt.
