Technological evolutions on the Brazilian payment market

Things are moving on the Brazilian payment market. Not only does the legislation have a impact. technology is is also ever evolving. Mobile and contactless payments are getting more prominent. New cards, phones and devices are all equipped with these new technologies. 
In this article we will discuss some new developments that will shake up traditional players in the bank and POS hardware sector.

Cooperation between VeriFone and Paypal
VeriFone has PAYware Mobile, a platform developed for the iPhone (and iPod touch). Thw mobile solution consists of a software application and a sleeve with card reader that connects to the dock connector. Now a deal with PayPal allows these mobile payments devices to accept PayPal transactions. This means transactions will be possible without using the traditional merchant network, which is especially interesting for small businesses.
Another part in this story is Bump, a technology that uses Near Field Communication to connect devices. For example an NFC smartphone will be able to connect with a VeriFone terminal equipped to receive such transactions.

Cielo develops for iOS
Cielo developed an application for the iOS platform, the operating system that runs on iPad, iPhone and iPod devices. It allows small merchants or freelancers to charge without the need for any extra devices or contracts. Charges per transaction, with a monthly minimum of R$ 9,90 (about 6 dollars). All the needed information is the value of the transaction, number of payments, card number, expiration date and security code of the client.
Cielo is working on an integration with Oi Paggo, the mobile platform that they are building together with Banco do Brasil and mobile carrier Oi.

Square out of beta
Square provides a card swiping device that connects to the headphone jack of a mobile phone. The device is free and Square charges per transaction. The company is now offering their services to the general public.
Its primary market consists of small independent traders who are wooed by the promise of cheaper transaction processing and set up costs than those found via traditional merchant terminals. 

Google develops mobile payment phone
Google developed a new phone equipped with a Near Field Communications (NFC) chip. When another device such as a point of sales terminal is equipped with a receiver, it enables electronic transactions in this way. The next generation of its mobile operating system Android, Gingerbread, will feature a mobile payment option.

These are just emerging technologies, but with a huge potential. They offer a way to avoid the traditional transaction processing network. And especially for small business, for whom the current system is expensive, this is an interesting evolution.
And also bring the POS hardware functions to new devices, mainly mobile.
