Analog Credit Card Terminals and Digital / Voice Over IP (VoIP) Phone Service



As the popularity of digital and VoIP phone service in today’s business market grows, so do the communication issues with analog machines. As a payment-services, sales professional it is imperative that you are aware of the issues relative to analog equipment and newer digital phone lines to be able to recommend the appropriate alternative solutions.


Analog credit card terminal modems run on an analog frequency that is much slower than a typical digital phone line frequency. Analog equipment has difficulty communicating over the static, line noise and echoes caused by the vast frequency difference between itself and a digital phone line. Ultimately, duplicate transactions, multiple authorizations, transactions that never get processed and modems that wear themselves out are common results. Not-to-mention the initial download of the machine can be a problem.


In many instances, persistence or a DSL filter have become acceptable “work-arounds” for the problem and merchants with analog equipment and digital phone service continue to process. An issue that most merchants and many sales offices are unaware of is that utilizing a PCI Compliant terminal with a standard VoIP connection deems their processing “Non-compliant” with PCI standards.


A PCI Compliant terminal with encrypted VoIP may be compliant if the connection meets requirements of all published Visa and MasterCard (and any other types of cards that you are going to swipe) data security rules, including encryption and firewalls. It must also meet the standards as outlined for your type of business at https://www.pcisecuritystandards.org/.


This issue is obviously not limited to new business. Existing merchants who have upgraded their analog phone systems to digital are also experiencing frustration with this problem and should be informed of the issues and given the proper options for resolution.


So what are the options? The easiest, but not necessarily the least expensive, solution is to replace the old, analog credit card terminal with an IP-capable device running over an Ethernet connection. Examples of acceptable devices would include the Verifone Vx510 Dual-Comm (both 6 mb and 12 mb) unit or the Vx 570 DC terminals. In some instances it may make sense to suggest a wireless solution such as the Verifone Vx610, PAYware Mobile or Charge Anywhere products. Finally, in others instances a PC-based virtual terminal or client side software solution with a USB mag-card reader may be the best choice.

It is important that you understand the problem and are familiar with all of the possible solutions in order to help your merchants make the best choice. Please feel free to contact our offices to further discuss the issues resulting from digital and VoIP phone systems.

  1. I work for the Bus Services Dept of a Cable service provider. My problem is with digital telephone to analog CC terminals. We install digital telephone over coax lines that usually have no problem working everyday. Most of the time when there are CC issue we have packet loss in the wiring or outside plant and when it is isolated and repaired the CC and fax service is restored, I have recently run into problems with Verifone Omni Credit card terminals. For some reason these are the most common terminals having issues with lost connection, failed batches, poor line ect. The outside plant and IW coax and twisted pair have been troubleshoot and seem not to be causing the issue.Other Verifone terminals and other brand terminals in the same office aren't having the same issue. I have been reading as much as I can to help the Co and Cust figure out the best solution. Your article and others talk about DSL filters. I don't believe this will help me with what I am working on but I haven't seen a lot of other solutions. I have googled and read up things like digital to analog converters VOIP and every other forum blog and discussion about CC's and Digital telephone. I have years of experience in Traditional telephone contracting splicing and I & R before coming to work for a cable provider 6 yrs ago. Any advise or knowledge that you can provide me would be greatly appreciated and used to provide above and beyond cust service that I work hard at providing every day to the customers that I come in contact with .

    Thank You Patrick
