The problem becomes evident upon a power cycle/reboot of the terminal. The screen will remain blank and the terminal will emit 3 beeps.If you experience the problem, please call our Customer Care Center at 888-288-2692.

Change in Password Policy

Password security is a key component of a strong data security policy. Beginning in January, users who log into the Business Platform to review transaction activity will be required to comply with the following new password requirements:
  • Passwords will need to be a minimum of 7 characters, contain at least one alpha and one numeric character, and cannot be the same as the previous 4 passwords.
  • Users will be required to change their password every 3 months.
  • Users will be automatically logged out of the system after 15 minutes of inactivity.
  • Users will be locked out after 6 failed attempts to login. Note: the account will automatically unlock after 30 minutes, or the user can contact Customer Care for help.

ACTION MAY BE NEEDED: Change of IP Address

Merchant e-Solutions will provision a new block of IP addresses across our datacenter footprint that will enable us to build scale and have better management and portability for future expansion. This will impact merchants that have programmed their own shopping cart or POS system directly to our processing network, or who are using a 3rd party certified shopping cart solution or POS using our API code.

If you have a firewall and/or have hard-coded to our systems, you are required to update your devices and/or applications to point to our new IP address in order to avoid loss of connectivity to the Merchant e-Solutions platform. Please refer to IP address mapping details below.
Failure to make this update by January 21, 2016 may result in the inability to process transactions.

If you connect to us by solely using one of the following, you should not be impacted; however, you are still encouraged to check with your system developer to verify: stand-alone payment terminal, Virtual Terminal retail PC app, Virtual Terminal mobile app, Netsuite, or Authorize.net via the TSYS gateway.

If you have integrated payments into your systems via an API by hard-coding an IP address to our processing platform, you must update to an appropriate new IP address as outlined below. Test your application connectivity to ensure that everything is working as expected.

Security Advisory: This advisory notification is to make you aware that there have been reports of phishing e-mails (emails asking for the recipient to provide personal information) circulating that appear to come from Merchant e-Solutions. These e-mails attempt to direct you to a website that is wrongly posing as Merchant e-Solutions and looking to steal your user name and password as well as other personal information. Use caution when receiving any e-mails with links asking you to log in and which could result in the disclosure of your user name and password to others. Be sure to check URLs (website addresses) carefully as users with malicious intent often use websites with names that seem familiar but are slightly different. Also check the SSL certificate of the site to ensure you are on the correct site. When logging into Merchant e-Solutions, the best approach is to go to www.merchante-solutions.com and click on the Login button. If you receive emails with suspicious links, please delete the emails.
