Extract (parse) Amount And Description From BIZ (Transaction) Sms

I am doing below steps. match sms with regex if contains specified keyword then get values from sms body like amount,description (reason of transaction), Account number(if ATM wit

Solution 1:

For finding out amount from bank transaction message.

(?i)(?:(?:RS|INR|MRP)\.?\s?)(\d+(:?\,\d+)?(\,\d+)?(\.\d{1,2})?)

For finding out merchant name from bank transaction message.

(?i)(?:\sat\s|in\*)([A-Za-z0-9]*\s?-?\s?[A-Za-z0-9]*\s?-?\.?)

For finding out card name(debit/credit card) from bank transaction message.

(?i)(?:\smade on|ur|made a\s|in\*)([A-Za-z]*\s?-?\s[A-Za-z]*\s?-?\s[A-Za-z]*\s?-?)

Solution 2:

In python following Regex can be helpful.

For finding amount in bank messages

[rR][sS]\.?\s[,\d]+\.?\d{0,2}|[iI][nN][rR]\.?\s*[,\d]+\.?\d{0,2}

For finding A/C no

[0-9]*[Xx\*]*[0-9]*[Xx\*]+[0-9]{3,}

Solution 3:

The following two regular expressions helped in finding amount from most of the bank transactions(HDFC, ICICI, ING, KOTAK, SBI, CANARA, PNB):

[Ii][Nn][Rr](\\s*.\\s*\\d*)
[rR][sS](\\s*.\\s*\\d*)

Please comment if you have figured out much better expressions than the above.


Solution 4:

To detect any transactional message in android :

"(?=.*[Aa]ccount.*|.*[Aa]/[Cc].*|.*[Aa][Cc][Cc][Tt].*|.*[Cc][Aa][Rr][Dd].*)(?=.*[Cc]redit.*|.*[Dd]ebit.*)(?=.*[Ii][Nn][Rr].*|.*[Rr][Ss].*)"

tested on several bank messages


Solution 5:

Please check https://github.com/minimal-scouser/trny

Usage:


import { getTransactionInfo } from "trny";

const message = "Your a/c XX0413 is debited on 15/12/2020 by INR 3,211.00 towards purchase. Avl Bal: INR 5,603.54.";

const info = getTransactionInfo(message);
 
/* 
info = {     
   account: {
    type: "account",
    no: "0413"
   },
   balance: "5603.54",
   money: "3211.00",
   typeOfTransaction: "debited" 
}
*/

It also has methods like

  1. getAccount
  2. getMoneySpent
  3. getBalance

This needs more testing but see if this solves your problem.
