1. As compared to other methods of automated recognition (such as fingerprints or facial recognition) this method is expensive to implement and maintain as the equipment is costly.
2. The user has to remove his/her glasses in order to make the eye available for scanning. Some people may not be comfortable with removing their glasses and resent the fact that a sensitive part such as the eye has to be brought into close proximity of an electronic scanner.
3. Some individuals may not want to allow a machine to store information regarding their body and may consider it as a violation against their privacy.
4. The measurement accuracy of the scanner can be affected if the user suffers from a disease of the eyes such as cataracts. The measurement can also be obscured by eyelashes, lenses, reflections.
The Pros and Cons of Biometrics
Retina scans for better security
1. The retina/iris is universal and unique, meaning that all individuals possess one and it is distinctive to them. It is a permanent characteristic since the retina or iris pattern of a human stays constant over time.
2. The retina scanning machine accurately and easily collects the data which is to be collected and stores it.
3. The technology allows fast and speedy verification of the identity of an individual and therefore saves time.
4. It is hard to deceive this technology since it is impossible for an individual to somehow alter the image of their retina or iris to match someone else’s.
5. Retinal scanning is also a fairly acceptable method of collecting biometric information and is not considered to me a massive intrusion upon privacy for most individuals, although some consider it to be intrusive.
6. This method also has a very low false acceptance rate and false rejection rate, which implies that most of the time it is absolutely accurate and seldom makes errors.

Retina and Iris Identification
This technology is also proving to be quite useful to doctors as it allows them to detect multiple diseases in a patient just by the use of a retinal scan. Previously, many different tests needed to be carried out before the doctor could reach a conclusion regarding what was wrong with the patient but now many diseases and conditions including malaria, AIDS, syphilis, Lyme disease, and chicken pox all show up in your eyes and can therefore be determined by a retinal scan.

Biometric devices are used to electronically verify the identity of individuals or recognize them using various biological traits. Using these devices, we can use our fingerprints, handprints or voices to gain access to computers, rooms, online accounts etc. We can use ID cards or passwords for personal identification but both these methods are susceptible to being lost or stolen. Biometric devices use physiological or behavioral traits in humans which are unique to them and therefore serve as a great measure for identity recognition or verification. This blog will discuss the purpose and usefulness of biometric devices that use retina and iris scanning to identify people. This technology functions on the basis of enrollment and testing. First aperson enrolls his/her biometric information (a digital image of the scanned eye) which is stored by the device for later comparison. Then later on when they provide their retinal scan to gain access to a restricted area/workstation, the scanned image of their retina is compared to what was previously stored on the machine. If there is a match then they are granted access, if not then they are rejected. Iris/retina scanning is an effective way to recognize or verify the identity of an individual since no two iris patterns are alike, in fact, studies show that the probability of two fingerprints being alike is higher than that of two iris patterns being alike.
