Detecting throw away and virtual Credit Cards


Detecting throw away and virtual Credit Cards

it should still fix some issue The pre-auth will not solve this issue. Throw away cards will pre-auth successfully, so don't allow a way to differentiate between temporary cards and long term cards.
Pre-authing itself has a number of issues, the main one being that each card issuer will hold the pre-auth value for a varying amount of time, anywhere from 2 days to 30 days. This can lead to issues where you either pre-auth too frequently (which really annoys the customer, because it looks like money is constantly dripping from their account) or not frequently enough (so that the pre-auth drops off and you have no guarantee the funds are available when you actually want to take settlement)

Storing credit cards, an alternate to using a credit card vault

Storing credit cards, an alternate to using a credit card vault

I wish did fix the issue. For anyone curious about what we decided to do. We decided to support payment gateways with a credit card vault. Each card is stored with each gateway. So if we charge a card on gateway #1, it gets stored in gateway #1's credit card vault. If we charge that same card on gateway #2 we require the user to enter their card again and store the card there.
After doing some research, storing cards on our server was simply not an option and the risk associated with it outweighed the benefits. PCI compliance is something our clients relied on us to provide.

Does that help As noted, you can't legally store that data in your app without major effort and expense to comply with PCI requirements.
That's one of the main selling points of services such as Stripe: they store all that data for you, and thereby remove that legal burden from you.
EMV cardholder name is different to name on credit card for NFC scanned credit cards

EMV cardholder name is different to name on credit card for NFC scanned credit cards

it should still fix some issue Both, the name that you read from the card and the name that's printed on the card are infact the same. The printed name is typically printed {FIRST NAME}{SPACE}{LAST NAME} whereas the card holder name field in the card's data structures (e.g. mag-stripe track data) is always encoded as {LAST NAME}/{FIRST NAME}. So to get the name printed on the card you can simply split the string at the "/" (slash) to get the first name and last name fields. You can then re-arrange those fields in whatever form you need.
Btw. note that all major brands committed to removing the name information from the data structures readable through the contactless interface. Thus, with future cards, reading the card holder's name through NFC will not be possible any more.

seems to work fine Depending on what you are doing you may need to comply with a standard like PCI, PADSS, etc.

Search Credit Cards in MySQL

Search Credit Cards in MySQL

will be helpful for those in need MySQL regular expression syntax doesn't use \b for word boundaries, it uses[[:<:]] and [[:>:]]. It doesn't use \d for digits, it uses [[:digit:]]. It also doesn't have ?: prefix in groups -- they're not needed because it doesn't have back-references, so there's no difference between capturing and non-capturing groups.
But the reason for your error message is that it doesn't have non-greedy quantifiers like *?.
code :
SELECT *
FROM reports
WHERE content RLIKE '[[:<:]]([[:digit:]][- ]?){13,16}[[:>:]]'
