The Galaxy Nexus will be hitting the shelves this Friday, however the smartphone will be lacking a certain feature for Verizon Wireless (News - Alert) customers.

Reports of the device being devoid of Google Wallet are, in fact, true. Despite the fact that the Nexus is an Android device, Android being a Google (News - Alert) product, Google Wallet will not be supported because Verizon is building its own payment system.

The Galaxy Nexus has the necessary component to make Google Wallet work - one functioning NFC chip – but ISIS, the mobile payment project for Verizon Wireless, is to blame for the blocked Wallet service.

It looks like Verizon and the other cell phone carriers want to push ISIS and don’t want any competition on the phones.

This isn't the first time Google Wallet has been blocked. It's also unavailable on Nexus S devices on AT&T and T-Mobile (News - Alert), due to their aforementioned support of ISIS. Samsung, HTC, LG, Motorola, RIM and Sony Ericsson are also backing ISIS.

This omission was confirmed by Computer World’s JR Raphael, whom cites a Google spokesperson as giving the official word, saying it was ultimately Verizon’s decision to nix Google Wallet compatibility.

Google Wallet is an app that allows users to make payments, redeem digital coupons and earn points with merchants. This app allows Google to compete in the local-business advertising market.

Cantaloupe Systems is gearing up to launch Google Wallet in vending machines across Chicago, San Francisco, New York and D.C., according to All Things Digital.

So far the Bay Area start-up has installed NFC technology into 6,000 of the 80,000 vending machines in its network. Once complete, customers will be able to pay for drinks and snacks with a simple tap of their phone.

In addition to greater convenience, the new service could introduce coupons and rewards offers into the vending machine industry. Mobile apps could even allow customers to submit requests for items or complaints about machine malfunctions directly to operators.
