Id Card Reader Writer Software Download Nfc Card
Contactless smart card reader/writer Until recently, reading credit card data was as easy as swiping a card through a reader (such as one of the many readers made by ID TECH) and having a virtual-terminal app (or other apps) slurp up the track data as it comes straight out of the reader. System Utilities downloads - NFC Port Software by Sony Corporation and many more programs are available for instant and free download. The data in question would simply show up as keystrokes on a screen, unencrypted.Download nfc card reader software for free. The extension eliminates the need for complicated programming with SDKs making it simple to securely capture and process sensitive payment and ID card data.Until recently, reading credit card data was as easy as swiping a card through a reader (such as one of the many readers made by ID TECH) and having a virtual-terminal app (or other apps) slurp up the track data as it comes straight out of the reader. Wedget is a developer tool/extension to simplify card data acquisition for mobile browsers and native applications for MagneSafe® secure card reader authenticators (SCRAs).
Also, it’s invariably encrypted.I got my NFC reader/writer on NewEgg, which lists it as NFC ACR122U RFID reader/writer tool. Chip card data takes the form of TLVs (tags, length, values) and can look quite a bit different from the “plain old magstripe data” of years past. Today, magstripe readers generally output encrypted data, over USB (often in HID mode, rather than keyboard mode), and most card readers today have to handle chip cards in addition to magnetic-stripe cards. The ACR122U NFC Reader is a PC-linked contactless smart card reader/writer.Suffice it to say, things have changed.

The fastest way to decode it is to run the data through ID TECH’s free Parsomatic tool, which is an HTML form that can render all the pieces of data in an intelligible fashion.Every card reader has its own proprietary way of representing card data. Most of what you’re seeing here is a hexadecimal representation of the binary data coming out of the reader.Parsing this big block of stuff is easy if you know-how. If we swipe the Starbucks card through ID TECH’s Augusta card reader operating in keyboard mode, with Notepad window open (and the cursor in the text window), we get the following data in Notepad:02ED01801F4C2800839B%*6010********8765^0254/SERVICERECOVERYUSD^*******************************?* 6010********8765=********************?*95025C86987E4F7DD07D58730EB79FDFB90AB7F23E6ECA6F4F04A67BF511EE13F950903BDE77624680C460E9C36C4F9136256BB93A38CB98F95626DCFAF9335CE0A213074CC1CD84CC911398E06756C464AB036B694228ADA7EC018F495A013AF8A04C976288FE2F80271E6E53D987DE19ACA2707BFF2C78000000000000000000000000000000000000000000000000000000000000000000000000000000003631335435333536313862994900750002A00308108E03This is a lot more than “raw track data.” You can recognize the masked track data (which begins with B% and contains many asterisks, finally ending in ?*), but that conceals the Primary Account Number (PAN), which is actually encrypted. It’s true, you might only be interested in obtaining (say) raw Track 2 data, but in the process of obtaining it, you’re going to have to deal with lots of other data, too.Let’s take a quick look at a real-world example using a Starbucks gift card given to me by a guilt-ridden barista as a makegood after unexpectedly running out of Mesopotamian Kumquat-Absinthe Latte. You’re also obtaining a KSN (Key Serial Number), which is needed for decryption, and harvesting various kinds of metadata pertaining to the transaction.
Track Status (value: 0x1F) is a status byte containing eight-bit flags, to let you know which tracks were present on the magnetic stripe (there can be up to 3) and which ones were read successfully. The Card Encode type is 0x80, which (in English) means our reader considers this is a financial card. The next two bytes (ED 01) represent the length, in hex, of the overall data payload (little-endian: ED 01 actually means 0x01ED or 493 bytes of data). According to Parsomatic, these 5 bytes contain the following information: STX-0- 1: Field 10 optional bytes length exists (0: No Field 10)-0- 1: Track 3 sampling data exists (0: Track 3 sampling data does not exist)-1- 1: Track 2 sampling data exists (0: Track 2 sampling data does not exist)-1- 1: Track 1 sampling data exists (0: Track 1 sampling data does not exist)-1- 1: Track 3 decode success (0: Track 3 decode fail)-1- 1: Track 2 decode success (0: Track 2 decode fail)-1 1: Track 1 decode success (0: Track 1 decode fail)The first byte (02) is simply STX, the “start” byte. The format includes 26 fields of data all 26 fields are described in detail in document P/N 80000502-001, ID TECH Encrypted Data Output.To give you an idea of what’s on the card, let’s consider the first 5 bytes of data (02 ED 01 80 1F).
(Track 3 had zero bytes.) These lengths are important to know, not only for parsing out the masked track data but for determining the lengths of the encrypted versions of the tracks. In this case, we’ve got 76 bytes (hex 0x4C) of data for Track 1 and 40 bytes (0x28) of data for Track 2. (First byte of service code was '2' or '6'.) Use EMV transaction if possible.-0- Bit 3: 1 if fixed key 0 DUKPT Key Management-0- Bit 2: 1 if Track3 clear/mask data present-1- Bit 1: 1 if Track2 clear/mask data present-1 Bit 0: 1 if Track1 clear/mask data present-0- Bit 5: if 1, track3 hash data (SHA digest) present-1- Bit 4: if 1, track2 hash data (SHA digest) present-1- Bit 3: if 1, track1 hash data (SHA digest) present-0- Bit 2: if 1, track3 encrypted data present-1- Bit 1: if 1, track2 encrypted data present-1 Bit 0: if 1, track1 encrypted data presentOn a financial card, Track 1 can be up to 79 bytes long Track 2 can be up to 40 bytes long Track 3 can be up to 107 bytes. According to Parsomatic, those bytes, and their meanings are as follows: Track 1 Length1- Bit 7: 1 Serial Number present 0 not present-0- Bit 6: 1 PIN Encryption Key 0 Data Encryption Key-0- Bit 5: 1 Chip present on card.
If you click the link, it takes you to ID TECH’s Encrypt/Decrypt Tool, where the data in question can be viewed in decrypted form.The final fields of data include the Reader Serial Number, the Key Serial Number (KSN), an LRC, a checksum, and ETX (end of transmission). Note that Parsomatic has converted the ASCII track data to a hex representation below: Track1 Data25 2A 36 30 31 30 2A 2A 2A 2A 2A 2A 2A 2A 38 37 36 35 5E 30 32 35 34 2F 53 45 52 56 49 43 45 52 45 43 4F 56 45 52 59 55 53 44 5E 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 3F 2A3B 36 30 31 30 2A 2A 2A 2A 2A 2A 2A 2A 38 37 36 35 3D 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 3F 2A95 02 5C 86 98 7E 4F 7D D0 7D 58 73 0E B7 9F DF B9 0A B7 F2 3E 6E CA 6F 4F 04 A6 7B F5 11 EE 13 F9 50 90 3B DE 77 62 46 80 C4 60 E9 C3 6C 4F 91 36 25 6B B9 3A 38 CB 98 F9 56 26 DC FA F9 33 5C E0 A2 13 07 4C C1 CD 84 CC 91 13 98 E0 67 56 C4 Decrypt this data64 AB 03 6B 69 42 28 AD A7 EC 01 8F 49 5A 01 3A F8 A0 4C 97 62 88 FE 2F 80 27 1E 6E 53 D9 87 DE 19 AC A2 70 7B FF 2C 78 Decrypt this data00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00Notice that Parsomatic inserts a “Decrypt this data” link next to encrypted data (see above). There’s also an Encrypted/Hash Data Sent status byte (shown above) to let you know whether encrypted track data (and validation hashes) are present and whether a KSN exists.Now we get to Track 1 and Track 2 masked data, followed by the encrypted versions of those, followed by some hash data (in this case, all zeros), and some other data (described below).
But this should get you started if you’re trying to decode data coming out of an ID TECH credit card reader.For more information, be sure (as I said earlier) to consult our technical documentation on the Enhanced Encrypted MSR data format: ID TECH Encrypted Data Output. Nor have we said anything about EMV data (which is definitely going to take another post). (They’re somewhat easier and quicker to calculate than a proper CRC.) ConclusionSo as you can see, there’s a lot more to a magstripe data than “track data.” We haven’t even touched on the significance of some of the data fields (maybe we can go there in a future post). The LRC and checksum can be used to check the integrity of the data payload.
