Developing for EMV, Part III
In Part I of this series, we talked about how chip-card transactions differ from magstripe. We saw that there’s a considerable amount of back-and-forth communication between the reader and the card.

ID TECH makes and markets a wide variety of payment devices, almost all of which, nowadays, are compatible with “chip cards” (or “smart cards”).
Read postUnattended Payment Solutions: What You Should Know
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.
Read postFalling Back to MSR with a Keyboard-Mode EMV Reader
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.
Read postUnderstanding Terminal Types
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.
Read postGetting Started with ID TECH’s Universal SDK
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.

ID TECH makes available a number of excellent free utilities for anyone involved in developing payment apps using our products.
Read postTools for Payment Device Integration: UDemo
Payment-app developers who need to fast-track the integration of ID TECH card readers into their POS (or other) systems can make headway quickly by taking advantage of ID TECH’s Universal SDK.

Integrating a payment peripheral into a POS app (or other payment app) can be challenging, even under the best of circumstances.
Read post“Can You Sell Me a PCI DSS Certified Reader?” is the Wrong Question
Here at ID TECH, we get a lot of technical questions about the payments business. People are sometime confused about Payment Card Industry requirements.

Many of ID TECH’s customers are interested in point-to-point encryption (P2PE), and as part of their quest to achieve compliance with PCI’s stringent P2PE rules, customers often consider SRED (Secure Reading and Exchange of Data) payment devices.
Read postHow to Calculate Checksum
Checksums of various kinds are commonly used in data communication protocols to allow the recipient of a message to determine, quickly and easily, whether the data is likely to have been corrupted in transit.

Getting a payment app up and running means being able to handle at least two different kinds of integration
Read postContactless Transactions the Easy way
Everybody knows what a pain in the “back end” chip cards can be. Insert your card, tap your foot, pray the chip misfires so you can go ahead and swipe…
Read postControl a Chip Card Reader with Your Browser!
If we tie together the USB connectivity code and Websockets code, it becomes possible for a web page to control a USB device using only JavaScript.
Read postConnect to USB Card Readers with Websockets
You can connect to any USB card reader from any web browser using Websockets and NodeJS. Which means you can do EMV transactions from a Virtual Terminal.
Read postHow to Parse TLVs in JavaScript
One of the nice things about chip cards (ICCs) is that the data that comes out of them is virtually always supplied in a standard format, called BER-TLV.

The Big Innovation here is that Augusta is the only chip-card reader on the market that can do EMV entirely in keyboard mode.
Read postRead a Chip Card in Two Seconds with Augusta
Faster EMV has the potential to turn a 20-second chip card transaction into a super-fast (2-second) “dip and go” scenario.
Read postAugusta with Quick Chip: A Faster Way to Do EMV
Wouldn’t it be great if a chip-card transaction took, say, 2.0 seconds instead of 20 seconds?We thought so too. Which is why ID TECH is proud to introduce the patent-pending Augusta with Quick Chip
Read postHow to Decode Magstripe Data
Until recently, reading credit card data was as easy as swiping a card through a reader and having a virtual-terminal app slurp up the track data as it comes straight out of the reader.
Read postEMV Device Configuration Essentials
Compared to magstripe readers, chip-card readers are fussy. Reading a magnetic stripe is comparatively straightforward, but getting a chip-card reader to converse with the chip on a chip card requires a substantial amount of preparation and setup.
