You've probably seen Identity Stronghold demonstrate on your local or national news channel how easy it is for thieves to steal your credit card information with a wireless scanner without even touching you. Over 200+ million cards have now issued with RFID. Maybe you have wondered if your credit cards and debit cards are susceptible? Find out with this app!
This app will not help thieves steal. This app only shows part of your account number as a precaution. But it is enough for you to know if your card can be scanned by thieves. We have crippled this app to not reveal the entire account number for consumer protection.
If your credit card does not contain RFID the app will just remain on "place phone on card" screen. This does not mean the app is not working just that your card does not have a radio chip in it yet. Please don't rate poorly for this reason as the app can only tell you when it finds and RFID chip, not when it doesn't. Thank you.
Not all credit cards and debit cards contain radio chips yet. Look for a WiFi type radio symbol on your card. If you have that symbol, your card DOES contain an RFID chip. Also each major card issuer has a different trademark so they may not always use the WiFi symbol.
The phones currently with NFC have a very short read range. Much shorter than the equipment thieves would use. So to test your card, set it on a non-metal table and with our app running set your phone on top of the card. It will take about 1-3 seconds to scan and show the end of your card number. If it does not detect your card, try moving removing the phone and setting it down on a different spot on the card. If it continues to not detect your card after two or three tries, your card likely doesn't have the new RFID chip embedded yet. But in the next 2 to 3 years most cards worldwide will be replaced with these new RFID versions, so you will have to watch your new cards when they come in.
This app will also detect some other RFID chips such as transit payment cards but not all RFID chips, as some operate on a different frequency. Particularly this app won't analyze state drivers' licenses, passport cards etc. It was primarily designed for credit and debit cards.
We have tested the app with US and Canadian credit and debit cards and a United Kingdom credit card. If you have a card from another country that you know has an RFID chip in it and it doesn't scan please email us and let us know what kind of card and which bank so we can see if they have a different format.
There may be a few credit cards that transmit a different card number than the one on the front of your card. Identity Stronghold has tested a few of these type cards and we were still able to complete purchases with that different number.
What does this all mean? Simply this. If you have one of these cards in your wallet or purse where someone in a crowd can get near your card, there is a chance that person could scan your credit and debit card info and steal from you.
It is up to you to protect yourself since the problem will only get worse as more of these new cards are issued. Identity Stronghold makes lots of different RFID blocking products to protect you such as shielded wallets, sleeves, and badge holders. The button on the screen that says "Protect Your Card" links you directly to the Identity Stronghold website where you can watch various news reports , read up on the technology and see the different products we offer for your protection.
Please show your friends as uninformed means unprotected....and the risk is as high as your credit limit...
This app was tested and works on Samsung Nexus S phones.
Many more NFC phones will be released shortly.
RFID = Radio Frequency Identification
NFC = Near Field Communications

The first ("direct") geodetic problem is defined in the following manner: given a point (in terms of latitude and longitude) and a direction ("azimuth") and distance from that point to a second point, determine the location (in terms of latitude and longitude) of the second point.
The second ("inverse") problem is defined in the following manner: given two points (in terms of latitude and longitude), determine the direction ("azimuth") and length of a line (in our case, both a geodesic curve (a great circle) and a rhumb line) that connects them.
*To solve the first ("direct") geodetic problem, simply enter the origin point, fill direction and azimuth fields and press the Calculate button.
*To solve the second ("inverse") geodetic problem, simply enter the origin and destination points and press the Calculate button.
*In order to change the units in which the input or output fields are given, simply choose a different measurment unit and press the Calculate button.
*Geoid Altitude output field rtepresents the height of the local geoid (EGM96 = Earth Gravity Model 1996) above mean sea level at the origin and destination.
*Forward output field represents the azimuth from origin point to destination point.
*Backward output field represents the azimuth from destination point to origin point.
*Direct output field represents the length of a straight line ("geodesic curve" / "great circle") connecting the origin and destination point, along the reference ellipsoid.
*Rhumb output field represents the length of a rhumb line connecting the origin point to the destination point, along the "meridional earth spheroid model" (radius of 6367.445[km]).
*Latitude and Longitude output fields represent the location of the point located at a given azimuth and distance from the origin point (they are given in degrees with a decimal notation).
*Origin and Destination points location can be entered in two different notations:
> degrees decimal notation: choosing "decimal" would require the location input field to be entered in degrees in decimal notation, eg.: 32.156845 or -4.563542.
> degrees/minutes/seconds notation: choosing "d/m/s" would require the location input field to be entered in degrees/minutes/seconds notation, eg.: 32 50 6 or -14 29 50. notice that a space should be enter between the degrees, minutes and seconds.
*Longitude is given in the boundary of [-180.0, 180.0] degrees. Negative longitude represents the western hemisphere and positive longitude represents the eastern hemisphere.
*Latitude is given in the boundary of [-90.0, 90.0] degrees. Negative latitude represents the southern hemisphere and positive latitude represents the northern hemisphere.
*If the origin and destination points are the same, than the distance between them would be zero, and the azimuth between them would be NaN ("not a number").
*If the distance entered by the user is such that the reference ellipsoid would be encircled, than the calculator would take it into consideration.
*Output fields are labeled using indent font, to seperate them from input fiields.
*Geoid altitude is calculated using a bilinear interpolation performed upon a 0.25 degrees grid of point value in a "tide-free" system. The Geoid is given relative ot the WGS84 ellipsoid. Maximum error in Geoid altitude is one meter.
*Rhumb line distance is calculated using earth spheroid radius of 6367435[km]. Deviation from other calculators might originate from the usage of a different earth radius.
The only atmospheric calculator that allows the complete and
exact calculation of each of the "1976 standard atmosphere"
28 parameters as a function of each of the other parameters!
Tired of calculating pressure or gravitational acceleration solely out of altitude?
well, now you can enter the desired pressure or gravitational acceleration and get the the atmospheric parameters which correspond to the lowest geopotential altitude. This is done for the entire 7 layers of the atmosphere (altitudes up to 84km / 280kft)
The atmospheric calculator parameters include:
- geometric altitude
- geopotential altitude
- lapse rate
- temperature ratio
- molecular temperature
- kinetic temperature
- mean molecular weight ratio
- mean molecular weight
- pressure ratio
- density ratio
- gravitational acceleration ratio
- gravitational acceleration
- dynamic viscosity ratio
- dynamic viscosity
- kinematic viscosity ratio
- kinematic viscosity
- speed of sound ratio
- speed of sound
- pressure scale height
- number density
- mean air-particle speed
- mean collision frequency
- mean free path
- thermal conductivity ratio
- thermal conductivity coefficient
- mole volume
Each of these parameters is given in metric and english units.
* Extrapolation is allowed(!) and performed for geometric altitudes from zero down to -5km.
* results for geometric altitudes between 80km and 86km are corrected for mean molecular weight ration which is not 1. Note that many 1976 standard atmosphere tables are not corrected according to the mean molecular weight ratio, but they do mention that this correction should be done.
p.s. network access is for ads.
* Enter a chemical formula the standard way.
* Symbols can be seperated by blanks.
* Simplified structures are also allowed.
* Formulas cointaining a multiplication (such as hydrates) should be entered without the dot.
* Numbers composed by an integer and a fraction (like 1 1/2) should be replaced by a fraction (3/2) or using decimal notation (1.5).
* The chemical formulas are case sensetive.
