Abstract
Abstract A method and device for storing data comprises a non-volatile memory for storing digital data words and a photoelectric transducer receptive of light energy applied thereto for producing an electric signal. The device is responsive to the electric signal for reading the stored digital data words out of the memory and for displaying the stored digital data words read out of the memory.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
100 words
A data storage system comprising: (a) a housing containing: a memory for storing digital data words; photoelectric means receptive of light energy for producing an electric signal; memory control means responsive to the electric signal for sequentially reading data words out of the memory; and display means receptive of the data words sequentially read out of the memory for displaying each data word as a bar code; and (b) means for applying light energy to the photoelectric means for effecting the sequential reading of stored data words and including means for reading the bar codes displayed by the display means.
Claim 2
Dependent Claim
100 words
A data storage system comprising: (a) a housing containing: a memory for storing digital data words; photoelectric means receptive of light energy for producing an electric signal; memory control means responsive to the electric signal for sequentially reading data words out of the memory; and display means receptive of the data words sequentially read out of the memory for displaying each data word as a bar code; and (b) means for applying light energy to the photoelectric means for effecting the sequential reading of stored data words and including means for reading the bar codes displayed by the display means.
Claim 3
Dependent Claim
12 words
The system according to claim 1, wherein the memory comprises an EEPROM.
Claim 4
Dependent Claim
14 words
The system according to claim 1, wherein the memory comprises a read only memory.
Claim 5
Dependent Claim
12 words
The system according to claim 1, wherein the memory comprises a RAM.
Claim 6
Dependent Claim
13 words
The system according to claim 1, wherein the memory comprises a shift register.
Claim 7
Dependent Claim
29 words
The system according to claim 1, wherein the housing is thin and planar and has an exposed surface of the photoelectric means and the display means at one surface.
Claim 8
Dependent Claim
14 words
The device according to claim 6, further comprising an adhesive layer on another surface.
Claim 9
Dependent Claim
15 words
The device according to claim 6, further comprising a transparent layer covering the exposed surfaces.
Claim 10
Independent Claim
70 words
A method for storing data comprising the steps of: providing a memory in a housing having digital data words stored therein; applying light energy to the housing and converting the light energy to an electrical signal; sequentially reading out data words from the memory in response to the electric signal; displaying each data word as a bar code on one surface of the housing; and reading the displayed bar codes.
Claim 11
Independent Claim
70 words
A method for storing data comprising the steps of: providing a memory in a housing having digital data words stored therein; applying light energy to the housing and converting the light energy to an electrical signal; sequentially reading out data words from the memory in response to the electric signal; displaying each data word as a bar code on one surface of the housing; and reading the displayed bar codes.
Claim 12
Dependent Claim
25 words
The method according to claim 9, wherein the steps of applying light energy and reading the displayed bar code comprise using a bar code scanner.
Claim 13
Dependent Claim
31 words
The method according to claim 10, wherein the steps of using a bar code scanner comprises using the same scanner for both applying light energy and reading the displayed bar codes.
