The joint venture between T-Mobile, AT&T and Verizon, Isis, will not be rolling out its trial as scheduled for the end of the summer.
Isis has announced that it delay the trials, planned to start in September in Utah, Austin and Salt Lake City.
Isis is attempting to launch a platform of mobile payments that will enable users to pay for services by simply waving at a POS terminal.
Isis is focusing on making sure that the launch is executed properly and that everything is working right.
The company does not explain why the project is delayed, claiming only that the wait would not be long.
Isis will not change its plans to become a provider that will allow merchants, payment networks and banks to run its system.
Rather than take a transaction fee for each transfer, the businesses will be able to charge for use of the system.
The Isis platform has attracted the attention of a number of companies, from PayPal to Visa, and many have agreed upon NFC technology, which will allow tap to pay option.
While a number of smartphones are already using NFC, including the Galaxy S III, the iPhone is an exception.
All the iPhone lack NFC, including the newly announced iPhone 5. An NFC iPhone would have made wonders for mobile payments adoption.
