iTransact is a payment gateway and merchant account provider. Its services allow Internet, bricks and clicks, and traditional brick and mortar merchants to accept payments via credit, debit, and gift cards, as well as electronic checks (and/or check conversion) with check guarantee.
iTransact was founded in 1994 by the father and son team of G. Allen Sumsion and Mike Sumsion. Originally known as RediCheck, iTransact is one of the earliest providers of telephone-based check acceptance services. RediCheck made its services available on the Internet in the fall of 1995, making it one of the first providers of online check acceptance. In 2010, iTransact, Inc., merged with National Merchant Services LLC to form The iTransact Group LLC.
While electronic check acceptance remains one of the company’s service offerings, iTransact today is primarily a provider of credit card payment services to merchants. Businesses can obtain payment gateway service and/or a merchant account from iTransact.
