Over the weekend, Rite Aid and CVS quietly shut down Apple Pay in their stores.

They're cutting off Apple Pay because they're part of a consortium of US retailers — called MCX — that is launching its own mobile wallet, which will compete with Apple Pay. The MCX contract includes a non-compete clause that prevents member merchants from accepting other mobile wallets including Apple Pay and Google Wallet, according to sources familiar with the terms of the contract. 

We think this is a very minor setback for Apple. We believe MCX merchants will ultimately accept Apple Pay in their stores. 

Here's why:

1. Consumers want security more than ever. As a result of the many data breaches at US retailers over the past couple of years, consumers are looking for a more secure option to protect their payment card data. Transactions made with Apple Pay do not transmit sensitive data, so even if transaction data is stolen it is useless for making fraudulent transactions. In addition, Apple's fingerprint reader Touch ID makes authenticating a payment faster and more secure than entering a password.

2. Apple Pay has the merchant infrastructure. Apple says Apple Pay can already be used at around 200,000 merchant locations, many of which are large retailers. But that number will grow quickly because a security update set by the major credit card companies will require retailers to update their credit card readers by late 2015 if they haven't already. When the merchants make the upgrade, they'll buy terminals that can accept Apple Pay to cover their bases. apple pay mcx locationsBusiness Insider Intelligence

3. Apple Pay has the consumer infrastructure. Forty-two percent of American smartphone users have an iPhone and over half of them are due for an upgrade. Once they upgrade, they'll have Apple Pay-compatible iPhones. All of the top banks in the US support Apple Pay and 500 additional banks will support Apple Pay in the near-term as well.

4. Passbook users will adopt Apple Pay. A quarter of American smartphone users already use Apple's coupon and loyalty wallet Passbook and usage is much higher among people with iPhones. Apple Pay is integrated into Passbook: People who use Passbook will use Apple Pay because it is easier to use [...]
