Playing with a magnetic stripe reader tonight and seeing what's on some thought-to-be-expired prepaid cards. Lots easier to put the 16 digit number into a web page if you can copy that number from Notepad than if you're typing it in ;-) From Amazon $18.80 plus tax and ship:
www.amazon.com/MSR90-Magnetic-Credit-Reader-Deftun/dp/B01DUB4GVO
Yes, I also have a laser barcode scanner - great for adding books, music and DVDs to my catalogs when that item has a UPC code. If all you want is basic 1D UPC-type codes (no QR-style codes) then the scanners are relatively cheap: $15 plus tax/ship at:
www.amazon.com/Handheld-Automatic-Supermarket-Convenience-Warehouse/dp/B07F5HH75R
The mag stripe contains various info, depending on the type of card (credit, debit, prepaid debit, vendor gift, etc.). A card from Panera has PANER in the name field.
One example: M/C debit card
number name next four exp. date YYMM (2018 June) ; numbers repeat
%B5445435886062686^LAST/FIRST^180610100000077?;5445435886062686=180610110000077?
Checking the cards online, I found that the Red Lobster card had not expired and still had a little over $5 on it ;-) The amount is now noted on the back of the card and it's in the stack with the other restaurant gift cards. I made almost $0.10 per minute tonight ;-)
I haven't yet decoded the rest of the strings of numbers/letters. Some of it is probably available online but decoding things myself is a bit of a mind stretcher. And I know how to veryify that a credit card number is in fact a valid number - not valid card, just a valid number - that has it's own bit of decoding - either with pencil and paper or - much faster - a programmable calculator (TI 8? educational series is adequate) or with a program in any number of programming languages.
