EMV Tag Decoders - provides detailed information for some of the commonly used EMV tags: Tag 82 - AIP (Application Interchange Profile) Tag 8E - CVM (Cardholder Verification Method) List

Verification Value (PVV, 4 characters), Card Verification Value or Card Verification Code (CVV or CVC, 3 characters) • End sentinel — one character (generally '?') • Longitudinal redundancy check (LRC) — it is one character and a validity character calculated from other data on the track.

The tool decodes EMV TLV (tag-length-value) data and its individual tags, providing extended meanings for tags such as TVR (Tag 95) and Terminal Capabilities (Tag 9F33)

Calculate Visa PVV (PIN Verification Value) online with our Visa PVV calculator. Utilize the Visa PVV algorithm for secure and accurate PIN verification

EMV （最初是Europay、Mastercard、Visa）是一个与支付利益相关者合作创建可互操作的支付标准和技术的技术机构。一个示例标准是芯片卡/非接触式卡及其与之交互的支付终端，包括使用的加密技术。

EMV （最初是 Europay、Mastercard、 Visa) 是與付款利益相關者合作的技術機構，可建立互通的付款標準和技術。其中一個範例標準是晶片/非接觸式卡及其互動的付款終端機，包括所使用的密碼編譯。

Offset, PIN Verification Value (PVV – Visa), or PIN Verification Number (PVN – Identikey). In this document, we will use the term PIN Offset to generically represent any of these PIN verification methods. With a magnetic stripe card, the PIN Offset may be stored on the Track 2 of the card, or it may be stored on the issuer’s host system.

Decoding EMV data in BER TLV format. Generating PIN offset and verifying PIN by IBM 3624 algorithm. Generating PVV and extracting PIN by VISA PVV algorithm. Calculating CVV, CVC, iCVV, CVV2, CVC2. Parsing TLV data with tags and subtags definition. Encoding and decoding between PIN and clear PIN block. Calculating MKac, SKac, AAC/ARQC/TC, ARPC.

PIN PVV Calculator. The VISA method generates a PIN verification value (PVV). Similar to the offset value, it can be stored on the card’s track data, or in a database at the card issuer. This is called the reference PVV.

EMV tag search: Look up EMV tags in this handy database. Search by keyword e.g. for all tags that contain the word "currency" or "cryptogram" in the description, or look up a hex tag e.g "9F20". TLV decoder: Decode EMV TLV (Tag, Length Value) byte strings into their constituent tags and sub-tags. Useful for analysing APDU traces, responses and ...
