### positive identification | password:

Modern password
* are made of characters , letters and numbers.
+ Password: Computer security
  * Modern passwords are made of characters, letters and numbers. Sometimes a password will require a minimum number of characters. Usually this is from six to eight. Some websites allow only the use of letters and numbers, but no other characters on the keyboard. Websites also advise changing a password once a year or more often to prevent hacking. A person may be able to guess a password if it is too easy.

### positive identification:

Smart card
* Many smart cards are about the size of a credit card and can be issued by banks.
* are a European phenomenon, with penetration increasing in Asia and Latin America
  - form of digital cash
  - actually micro computers
  - already popular in Europe but are practically unknown in the United States
  - credit card sized plastic cards with an embedded microprocessor chip
* are credit card-size devices that work in much the same way as tokens
  - pieces of plastic embedded with computer microprocessors
* are credit card-sized cards that contain small computer chips
  - pieces of plastic with a computer microprocessor embedded within
  - new devices that provide even tougher safeguards
  - plastic cards the size of a credit card and contain one computer chip
  - programmable, and hence can be applied to all manner of purposes
  - small enough to be stored in a wallet or a cellular phone
  - small-embedded devices with strong security requirements
  - some of the most secure devices available today
* are the mean of payment to tranfer ecash, that is the mean of exchange
  - most effective and secure means of storing and using digital signatures
  - wallet sized cards that contain a computer chip and can perform multiple functions
  - wallet-sized cards that look like credit cards in size and material
* can also store value.
* can provide basic patient data like blood type, allergies, and medicines
  - identification, authentication and nonrepudiation for secure transactions
* can store digitised photographs and fingerprints or other biometric data
  - personal information and perform secure financial transactions

### positively charged ion:

Cation
* All cations have the same positive charge.
  * are one of the two types of ion. The other type is called an anion
  - also a part of certain organic compounds
  - less likely to leach out of soil but are difficult for plants to extract and absorb
  - negatively chanrged, and anions are positively charged
* are positive ions formed by the loss of electrons
  - ions, anion are negative ions
  - the positive charged nutrients in the soil
* attract anions more strongly than anions attract cations.
* become smaller atoms.
* binding thermodynamics are independently determined using isothermal titration calorimetry.
* formed from metals have the same name as the metal.
* has center of inversion.
* have a positive charge.
* is an ion
* lose electrons and anions gain electrons
  - have an excess positive charge, e.g
* move from anode to cathode.
* positively charged ion.
* refer to positively charged ions.
* replaces in soil making the soil less fertile.
* tend to be surrounded by nearby anions and anions tend to be surrounded by nearby cations.
