Self-service or “unattended” credit card transactions are increasingly popular, not just at ATMs and gas pumps, but in a bewildering variety of other settings: pay-at-the-table terminals in restaurants,  tap-and-go public transit, airport kiosks, parking meters, vending machines, rental stations of all kinds, etc. Driven (in part) by technologies like Apple Pay and Google Pay, “self-service” has become one of the fastest growing segments of the payment industry as a whole. But note well, to succeed in unattended payments means more than just transplanting countertop credit-card acceptance technology to a kiosk enclosure. Think about it — unattended payment devices typically operate: Outdoors (no A/C, maybe no heat), possibly exposed to rain In locations with poor law enforcement coverage (thus, a built-in potential for vandalism) Where electrical power is at a premium; and/or In remote locations where maintenance is difficult or impossible ID TECH works with customers who, in some cases, have...

In previous posts, I’ve mentioned ID TECH’s patent-pending Augusta chip-card reader, which can run an EMV transaction in as little as 2 seconds using built-in “faster EMV” support (often called Quick Chip). What makes Augusta unique (and patent-pending) isn’t just the ability to do Quick Chip transactions. The patent-pending part has to do with the fact that these transactions can be done with a USB device operating in keyboard mode. That means: You simply dip your card, and character data (representing the TLVs needed for an EMV transaction) come streaming out of the device automatically, suitable for direct consumption by, say, a browser-based virtual terminal app. No special drivers needed. To integrate Augusta into a payment app, you don’t need any special software to “interrogate” the card reader. The reader simply outputs data automatically, upon card insertion. This mode of operation is already familiar to many users of magstripe readers...

When selecting a card reader, or before starting a Level 3 EMV certification, it’s important to know what kind of EMV terminal you will be supporting. The EMV Specs define fifteen different terminal types, depending on whether the payment environment is attended (such as in traditional retail) or unattended (e.g., a self-service kiosk), and whether the terminal goes online or stays offline, plus other factors. The terminal types defined by EMV are shown in the table below, which is taken from Annex A of EMV Book 4: ID TECH offers a wide variety of EMV-ready card readers, but not all of them fit into all of the categories defined above. ID TECH’s current offerings are certified in 5 categories (which we often refer to as 1C, 2C, 3C, 4C, and 5C). The mapping of ID TECH categories to EMV-defined terminal types is shown in greater detail below. Terminal Capabilities 1C...

One of the nice things about choosing a credit card reader made by ID TECH is that integration of the device into a POS or payment-app environment can happen quickly and painlessly via a single Software Development Kit, which we call the Universal SDK. It’s “universal” in that it exposes a common API across all supported ID TECH products, and works the same way regardless of environment. Having said that, it’s important to recognize that ID TECH’s Universal SDK comes in several flavors, depending on what kind of operating system you intend to deploy the device into, and the specific programming language you want to use. A C#-based (.NET Framework) Universal SDK is available to support most ID TECH products on Windows, but if you need to support, say, one of our Bluetooth VP3300 readers using a Samsung phone, there’s a Java-based Android version of the Universal SDK for that....

ID TECH makes available a number of excellent free utilities for anyone involved in developing payment apps using our products. In recent posts, I talked about Parsomatic, our free data parser (implemented as a web form), and UDemo, the Universal SDK test app that works with all of our non-legacy products (implemented in C# for Windows). I’d be remiss if I didn’t also encourage you to try our Encrypt/Decrypt Tool, which you can load in your browser by clicking this link. The Encrypt/Decrypt Tool is a powerful, self-contained single-page HTML app with a native JavaScript implementation of AES encryption, Triple DES, DUKPT key derivation, SHA hashing, HMAC, and much more. All the logic is contained in a single page (there are no server-side bits), which means you can download the HTML file and inspect the logic right in your browser (using, for example, Chrome’s excellent developer tools). As you can...
