Program great, easy to use. Difficulty processing payment. Had to call/email support to get assistance. That was super frustration when I was ready to finish up.

PDF Filler ease of completing the form - that makes it look much more professional than a hand written form. I like the ease of being able to put all my information in on any form. The software easily moves you from one field to the next to populate. Everything looks much more professional than a handwritten form. I don't like the fact that I cannot save my form. I can print it but it saves as a blank form. Maybe I am doing something wrong, since I just started using it, but it did not save what I put in.

For pdfFiller’s FAQs

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Payment card numbers are composed of 8 to 19 digits, as follows: a six or eight-digit Issuer Identification Number (IIN), the first digit of which is the major industry identifier (MID) a variable length (up to 12 digits) individual account identifier. A single check digit calculated using the Kuhn algorithm.
The Meaning of Each Digit. A credit card number is usually 15-16 digits long, but it could be as many as 19 digits or as few as 13 in some cases. Each of these individual credit card numbers has meaning.
Drop the last digit from the number. Reverse the numbers. Multiply the digits in odd positions (1, 3, 5, etc.) Add all the numbers together. The check digit (the last number of the card) is the amount that you would need to add to get a multiple of 10 (Modulo 10)
Validating a credit card refers to the process of running a computer algorithm that performs calculations using a credit card's number. When the algorithm shows that the card is valid, it means only that the card number is among those that could potentially exist with a given credit card company.
For Visa, MasterCard, and Discover cards, the code is 3 digits and is found on the back of the card. For American Express, the code is 4 digits and is found on the front of the card.
Making online purchases You would enter in your name, billing and shipping addresses (just use your shipping address for both), the gift card number (15-digit number on the front), card expiration date, and the 4-digit security code (located on the front of the card).
The first digit is different for each card network: Mastercard cards Begin with a 5 and has 16 digits. American Express cards Begin with a 3, followed by a 4 or a 7 has 15 digits. Discover cards Begin with a 6 and have 16 digits.
The first digit in your credit-card number signifies the system: 3 — travel/entertainment cards (such as American Express and Diners Club) 4 — Visa. 5 - MasterCard.
When accepting credit card numbers over the phone from customers, you can easily identify the type of card without asking the customer. While each credit card has a unique string of numbers, in varying lengths, the first one or two digits will reveal the issuer of the card.
3 — travel/entertainment cards (such as American Express and Diners Club) 4 - Visa. 5 - MasterCard. 6 - Discover Card.
First digit is 4 for VISA, 5 for Mastercard, 6 for Discover/Diners Club, 3 for American Express/Diners Club (those are shorter than 16). Also, first 6 digits for Visa and Mastercard are code numbers for the issuing institution.
Everyone in town has a Visa (starts with 4) with those digits. The last digit of every credit card number is the check digit. It is calculated from the prior 15 digits. So really, the unique account numbers are the middle 9 digits. If they re-issue your card, those will change (and the last digit gets recalculated).
First digit is 4 for VISA, 5 for Mastercard, 6 for Discover/Diners Club, 3 for American Express/Diners Club (those are shorter than 16). Also, first 6 digits for Visa and Mastercard are code numbers for the issuing institution.
American Express cards start with either 34 or 37. Mastercard numbers begin with 5155. Visa cards start with 4. And so on.
Card Number Lengths Most credit cards have 14 to 19 digits, and you can expect to see longer numbers in the future. For example, Visa and Mastercard cards are often 16 digits long, although shorter and longer numbers exist. American Express cards have 15 digits, and Discover cards have 16 digits.
