Transaction Network Services, Inc. Teams With Bell Atlantic Mobile To Provide Wireless Service For Credit Card Processors

July 22, 1998

BEDMINSTER -- Transaction Network Services, Inc. (TNS)
(NASDAQ:TNSI) announced today that it has signed an agreement with
Bell Atlantic Mobile to begin offering a seamless end-to-end wireless
solution for card processors who want to provide processing services to
merchants and vendors who do not have access to telephone lines.

The Bell Atlantic Mobile AirBridge® wireless data network will be
interconnected with TNS' TransXpress® X.25 network, eliminating the
need for merchants to use dedicated or shared telephone lines to carry
transaction traffic. Because there is no need for a physical "hook-up,"the
solution is particularly attractive to mobile merchants such as taxi and
limousine drivers, as well as in-home service providers such as plumbers,
electricians, and home delivery companies. Mall kiosks and sporting and
special event retailers, as well as fixed site merchants, will benefit from the
freedom of the wireless solution as well.

"Our decision to incorporate wireless data into our network services is
based on our ongoing commitment to offer processors new technologies
that will enable them to broaden their electronic merchant base,"said Brian
Bates, senior vice president and general manager of TNS' POS division.
"Moreover, we want to ensure that the implementation process, especially
when it involves new technology, is made as easy for our customers as
possible. We also want to ensure the same high level of TNS customer
support as processors bring up new technologies, so by offering turnkey
solutions, we can minimize customer effort and maximize customer
satisfaction,"Bates explained.

"This agreement with TNS is consistent with our strategy to focus on the
growing needs of the huge retail market for faster, cheaper credit card
processing," said Bill Davidson, vice president-wireless data sales and
marketing for Bell Atlantic Mobile. "Our AirBridge Wireless Retail
Solutions Group will work with TNS to provide merchants with flexible
options for conducting credit card transactions."
