Pilot 2 for RFinity testing is now in progress and will soon see the release of a sticker that takes the place of the micro SD card used to make purchases with cell phones.

The sticker is placed on the back of a phone and can be used as an alternate version of RFinity technology for phones that don’t have a micro SD card slot, such as the iPhone. It can also be used as a different method for phones that do have one. To make a purchase, a person would tap a reader at the cash register with the sticker on their phone.

“When you just walk up and tap it with the sticker, the reader excites the sticker so it sends a signal,” said Wally McPheters, the product manager for the RFinity technology on campus and the two pilot tests. “A number — but not an account number — that’s unique to that sticker is registered, and that goes through our server.”

Sometimes a purchase may require a PIN number, McPheters said.

The buyer would then use the quick pay option in their phone to complete the transaction. A receipt would be sent to their phone upon completing the purchase.

After the conclusion of Pilot 2, RFinity will begin testing cell phone to cell phone transactions. This method would allow people to buy from or sell to each other using their cell phones, eliminating the need for cash or checks. The buyer would wave their phone over the seller’s phone, receiving the request for sale.

 The buyer would then approve the sale and both buyer and seller would receive a receipt once the sale was confirmed and finalized, according to www.rfinity.com.
