Google Wallet’s security problems that surfaced last week—two different ways for a thief who has stolen a phone to get access to payment cards in the digital wallet—prompted Google to block new Google Wallet provisioning for several days until the company pushed out a fix. But the vulnerabilities also highlighted a major pain point: Shifting payments from plastic card to smartphone isn’t just about technology, it’s also about getting partners to cooperate—in this case, card issuer Citi.

The big problem: The most logical and secure technology fix—moving PINs to secure hardware—is something Citi seems unwilling to do.

Hewlett-Packard announced a new open-source Web browser for mobile devices on Tuesday (Feb. 14). It’s name? Isis. That’s the latest slap for ISIS, the mobile payment initiative backed by Verizon, AT&T and T-Mobile—apparently HP didn’t even wonder if anyone had trademarked “Isis” as the name for a mobile app (yes, ISIS has). It’s especially worrisome with ISIS now slipping into third place in the mobile payment horse race behind Google and PayPal, which are both already taking payments.

Even more confounding: Starting this month, Google now offers Google Wallet on some AT&T mobile phones and, unlike Verizon, AT&T is apparently officially allowing it. To be fair, ISIS still plans to start trials of its payments system this summer in Salt Lake City and Austin. But to be realistic, if ISIS can’t keep its founding members on board or even defend its brand name, you have to wonder whether these telcos still think they can win the mobile payment game—or if ISIS is about to change directions again.

A Seattle mobile payment firm is pushing for phone purchases to be done with no PIN, arguing that with this young a market, consumer convenience needs to trump security. Given its focus on authenticating the phone instead of the customer, it’s had to get creative and might be pushing the privacy envelope. It examines the five most frequently called friends, for example, along with a list of installed applications.

Whether or not its methods go too far, it’s in good company in the mobile early-stage convenience versus security argument, with both PayPal—and its phone-less and card-less purchases at Home Depot—and Visa, which is pushing PIN-less EMV transactions while MasterCard is taking the more secure and less convenient pro-PIN EMV position.

A new cryptographic hole revealed this week will impact one in 500 encryption keys, will be fairly hard for cyberthieves to find and will almost certainly be patched quickly. Still, it raises fundamental questions about encryption reliance. The group of cryptography researchers described an encryption hole that hits RSA especially hard, and at least one major chain is taking this very seriously.

“The bigger concern is internal keys, ones they couldn’t survey. Without their data of ‘weak keys,’ we can’t be sure we aren’t using any,” the retail exec said. “All owners of certificates do not know today if their keys are weak or not, and have no way of finding out just by examining them.”

In almost all U.S. state and federal data breach disclosure laws, a loophole lets a retailer avoid disclosure if law enforcement says it would help the investigation to keep the breach secret. The U.S. SEC, however, now has no such exemption.

This means that if the Secret Service or FBI tells a chain to keep an incident secret or else risk disrupting an active investigation, a company that complies—and keeps word of the breach out of SEC filings—may be guilty of SEC fraud, pens Legal Columnist Mark Rasch. In this federal agency versus federal/state agency situation, the retailer victim may be victimized again.

MasterCard has clarified its EMV push policies, saying its campaign will be focused solely on direct data breaches (as in a wide-scale attack on servers stealing millions of card numbers). Its second campaign will deal with individual fraud (as in consumers losing their cards and someone finding them and then running up charges).

But the number-two card brand also spoke of a near-term future where E-Commerce will be able to use the EMV chip to authenticate and process E-Commerce and M-Commerce transactions. However, will consumers pay more for laptops that can handle such security? And will tablets and smartphones—which can more easily and more cost-effectively handle such technologies—grow quickly enough to make desktop/laptop enhancements irrelevant?

When it comes to loyalty, many retailers are stuck in the 1990s. Does anyone else find it funny that in a world where you can very easily have a video conference with your kids from a $500 tablet over free Wi-Fi from a random hotel, we’re expected to keep a 3.3- x 2.2-inch piece of plastic in our wallets to get benefits from some of our favorite retailers?

All of this, pens Retail Columnist Todd Michaud, in an area—such as CRM—where the application of technology could directly impact a retailer’s top and bottom lines.

MasterCard’s Monday (Jan. 30) rollout of its roadmap for EMV in the U.S. set it on the opposite side of payment security from Visa, with MasterCard pushing for EMV with PIN and Visa arguing that PIN isn’t necessary. MasterCard is backing up its preference with some serious fraud-dollar forgiveness. Oddly enough, the much-smaller MasterCard has trumped—or, more precisely, nullified—Visa’s position, at least as far as retailers are concerned.

Given that greater-than-99-percent of Visa retailers in the U.S. also accept MasterCard, chains must go along with whichever brand has the more strict requirements. Typically, that’s been Visa, but not this time. On EMV-related PCI relaxations, however, the two brands opted to adopt identical policies.

For quite a few years now, the contactless payment world has enjoyed an endless-loop of defend-and-repel games when dealing with contactless security. The game starts with bank assurances that the data being transmitted wirelessly couldn’t possibly be enough for a thief to perform a transaction. Next is some public demo of a security researcher wirelessly grabbing data and completing a transaction. This is followed by industry refutations that the system demoed was either out-of-date or some part of the test was unrealistic.

Interestingly enough, there’s truth on both sides. But the dance of demo-and-explanation seems to never slow.

PayPal’s expansion of its in-store payments trial at Home Depot (up from 400 PayPal employees to all PayPal users) marks a huge jump in the trial’s scope—and risk. On January 19, PayPal opened up the trial to include 51 stores (up from the initial 5) and said all PayPal users could now sign up for the system. That should give both PayPal and Home Depot much more useful information on who will use the system, and how.

But PayPal’s approach—which essentially reverses 50 years of payment-card advances by eliminating any physical authentication device—still presents a big challenge when it comes to security. The ability to check out with just a mobile phone number and PIN—no plastic card, NFC-enabled phone or other authentication hardware required—means anyone who can acquire that phone number plus PIN has a free shot at the legitimate customer’s account.

When a customer walks into a store and gives a payment card to an associate, who charges it on a store-branded mobile device, is that customer interacting with that retailer? If that device is using Square, the answer is “no,” but the customer won’t know that. If an E-mail address is requested, is it for Square or that retailer?

If a marketing opt-in question is posed, who is posing it? And how will customers react when they later learn they weren’t sharing with whom they thought they were sharing? Bad news: This is not hypothetical. There is a broader issue at play here. With any of the third-party mobile payment efforts—Google Wallet, PayPal, ISIS, maybe even Apple—there is the potential for this type of confusion.

Historic British retailer Fortnum & Mason—with roots dating back to 1704—is finding that PCI compliance doesn’t end with IT. The chain had to confess last week that a customer service rep was asking customers to E-mail their full credit-card data—including CVV—to process routine refunds.

Clearly, one errant employee is something every chain has. But this example brings up a too-often overlooked PCI fact: Compliance is an issue for every employee. Mobile payment, being a disruptive factor, will only make things worse, because it creates many more opportunities for payment-card data to be captured/retained against the rules.

In the power struggle between retail marketing and retail IT, IT is getting its server farms kicked. It started with E-Commerce and is now growing with mobile and social. What has to go? If it can go in the cloud, get rid of it. E-Mail? Gone. Web hosting? Out of here. CRM? Exit, stage right. If it can be easily outsourced by specialist firms or even done by people in the business unit, you need to let it go.

It’s time to evict Web and mobile app development, and pretty much any marketing initiative that isn’t core to your business. Heresy? Certainly, pens Retail Columnist Todd Michaud. But it’s necessary.

Given that PCI only applies to payment transactions for the five major card brands, PayPal transactions would not normally be in scope. But recent pilot programs by at least one major retailer and an announcement by a POS device vendor has PCI Columnist Walter Conway questioning the conclusion that PayPal transactions will remain out of PCI scope.

If a PayPal card triggers a transaction on an underlying Visa or MasterCard, might that PayPal account be considered a “high-value token” and, therefore, be in scope for PCI? And if the PayPal account is in scope, is it a big deal?

With Visa’s clarification on January 13 that its U.S. EMV deployments will include Chip-and-no-PIN, retailers are trying to decide if this is a good thing or a bad thing. On the bad side, this forces retailers to immediately trust the chip technology perhaps a bit more than they want to.

“When I think about secondary validation, that gives me more of a warm fuzzy even though we have people saying that I have a more sophisticated chip and that my smart device has got some protection sitting in it,” said Bill Titus, the Loss Prevention VP at Sears.

When Amazon’s Zappos apparel unit announced on Sunday (Jan. 15) that more than 24 million customers had their information potentially stolen from its site, Zappos took the radical—but wise—move of wiping out all of its passwords. That caused massive disruptions to the company, shutting down customer service phone access and access to the site from outside the U.S., in addition to inconveniencing all customers.

But it was the unequivocal declaration that payment systems had not been touched that raised eyebrows. At this early stage of a breach investigation—knowing that cyberthieves tend to be quite good at hiding their tracks and creating misleading tracks—is such a blanket promise to customers reckless?

As retail rapidly moves to integrate mobile into almost every aspect of its customer interactions, many in IT and Loss Prevention are wisely scared about the security holes that will crop up during the rush. One such exec, William Titus, LP VP at Sears, said on Tuesday (Jan. 17) that one of his biggest fears involves mobile electronic receipts.

“The E-receipt problem is that the customer now has a valid receipt. I can’t bring it in. I’m not checking it off and signing off on it. So the ability to use that fraudulently increases unless you have a true returns management system,” Titus said.

If ever there was an argument where security trumped compliance, the debate about tokenization versus encryption is it. Readers have made that point abundantly clear following a recent column describing the PCI scope reduction benefits of tokenization versus encryption.

The shift in emphasis from compliance to being secure is not new, but PCI Columnist Walter Conway was struck by how pronounced a perspective change retailers are experiencing.

Mobile payment is going to change retail in an unknown number of unknown ways, and your lawyers will have healthy employment. Consider in-aisle checkout and shoplifting rules, pens Legal Columnist Mark Rasch. Today, customers who put products in a concealed place—a pocket, backpack, purse, etc.—while still in the store can be convicted of shoplifting even if they have yet to reach the POS checkout area.

The conceal part of that action is considered evidence of criminal intent. Now let’s see you try and enforce that rule when you have in-aisle mobile checkout.

This year—2012—will be the beginning of the end for the traditional POS platform. Even though many analysts predicted that Apple, and its iPad, would be the David that finally took down the Goliaths, Retail Columnist Todd Michaud is arguing that Google will land the fatal blow.

The POS defense has been that chains need hardened systems. That argument worked when tablets were $500 and even $400. But now that Android tablets have fallen below $100, the argument falls apart. You could have four spares in the backroom and still be ahead.

No retailer likes being fined by Visa or MasterCard for letting thieves steal payment-card data, and most grumble privately about how that process is arbitrary and rigged against merchants. But a lawsuit now unfolding in Utah has uncovered a remarkable level of detail about how arbitrary card brands can be.

The lawsuit is challenging everything from issuing banks’ contracts to Visa’s claims for counting up card fraud and pinpointing who’s to blame—in addition to $1.3 million in card fraud that Visa says the restaurant enabled via an alleged security breach for which there’s no concrete evidence.

Home Depot’s trial to let shoppers pay in-store with PayPal—a program confirmed late last week, which is loosely related to PayPal’s wallet—is interesting more for what it doesn’t do than what it does. It’s a baby-step program in two ways.

On the mobile front, it’s the first retail trial of PayPal’s mobile payment program and it doesn’t use a mobile device at all. (OK, that’s more an embryo step than a baby step.) On the payment front, this is also a test of Home Depot accepting a rectangular magstripe card that doesn’t say MasterCard, Visa, American Express, Discover or Home Depot on it.

Mobile wallets face a time-honored Catch-22: because very few stores support the technology, consumers have very little reason to bother getting it. Exactly how barren is this dial-tone desert for Google Wallet, currently the only actively being trialed game in mobile town?

We have our early clues from the CIO of the $2.5-billion 481-store Guess chain, one of the first test sites for Google Wallet in “a couple of stores” in California since May. In total, how many customers have tried Google Wallet? Says CIO Michael Relich: “Five or six.” Not 500 or 600 customers, mind you. Five or six.

Walk into one of about 25 Guess stores this week and you’ll see customer-accessible iPads in the men’s, women’s and accessories departments and even in the dressing rooms. “For the cost of a kiosk, I can put in four or five of these,” said Guess CIO Michael Relich. “This is the consumerization of IT.”

But the Guess iPad trial is hardly being done to save costs. The flexibility of the tablets and sharp, customer-friendly graphics make the devices a much more effective way to show demos and to locate merchandise, check inventory and do anything else that a kiosk would normally do.

In-aisle mobile payment isn’t merely a new payment method. It has the potential to force stores to rethink almost all aspects of operations—and few have seriously come to terms with how different environments are going to have to be. At the NRF show in New York City next week, a StorefrontBacktalk IT panel is going to map out the least-anticipated changes. And if you’re around on Tuesday 2–3 PM (1A 21/22 at the Javits Center), please drop by and tell us what we forgot to include. Ann Taylor CIO Mike Sajor, Sears VP/Loss Prevention Bill Titus and the NRF’s Joe Larocca—moderated by StorefrontBacktalk Editor Evan Schuman&mdashlwill look at the neglected items. As a Florida hobby shop discovered while serving as an NCR in-aisle mobile payment beta tester, this in-store mobile payment stuff is a lot harder than it looks.

“It’s really a change management problem,” Sajor said. “Literally everyone has to think through all of the possible change behaviors.” As Sears thinks through in-store mobile issues, it’s seeing how everything will need to change, from the supply chain to customer interactions to SKU-level integrity, inventory and dealing with new threats to the supply chain. “Some significant competitive advantages are going to be lost,” Titus said. The panel will be pure discussion, with no presentations and lots of audience interaction. So please argue with us there. Don’t make me come and find you.
